> To Get Citations Flying Again
Cessna Sends Trucks, Planes, and GO Teams
Some business jet maintenance organizations
have an aircraft that they can send for AOG situations. Some others have small mobile service
trucks for less urgent cases.
But, Cessna Aircraft Company delivers an incomparable package that includes an Air Response Team,
large heavily-equipped Mobile Service Unit trucks,
and even dispatchable GO Teams based at each
Citation Service Center.
“For specialized care that only the manufacturer can provide, the Mobile Service Unit is a
cost effective way to bring the service center
to the airplane, rather than the other way
around,” says Matt Nash, chief pilot of Westair
Corporation.
“This comprehensive package of mobile services
distinguishes Cessna Citation support from the
rest of the industry,” says Stan Younger, Cessna
VP of Service Facilities. “You can’t support the
world’s largest fleet of global business jets without being very mobile yourself,” he adds.
Each of the Mobile Service Units come complete with an extendable 28-foot boom capable of hoisting 6,000 pounds, well above
the necessary lifting power for the Citation X’s
Rolls-Royce AE3007s. Each has a diesel Ground
Power Unit, a compressor for shop air and lift
jacks for every Citation ever built. The truck
also has a rear-mounted lift for tooling and
parts, as well as, a hydraulic mule that lets the
truck cycle the landing gear.
Mobile Service Unit Trucks
Cessna leads the way in this new mobile world
of business jet support. From the first Mobile
Service Unit based in Texas, the Cessna Citation
Service Centers have deployed the specially outfitted trucks to other regions, including Arizona,
California, and North Carolina. More are set to
roll out soon.
Air Response Team
Cessna’s Air Response Team (ART) uses a Citation Ultra to respond swiftly to Aircraft On
Ground (AOG) situations for Citation customers in North America. The Air Response Team
was created to provide customers with the
parts and services they need when time is especially critical.
Each ground-based unit transports a team of
fully qualified Citation mechanics directly to a
customer’s aircraft, wherever that aircraft needs
support. This saves time and money for owneroperators because their Citations do not have
to be repositioned for service work. The specially
designed vehicles have nearly all of the capabilities of a fully-equipped service center, and each
truck even carries a boom capable of making engine swaps.
“A typical mission delivers parts to AOG aircraft. However, we have maintenance technicians standing by and are able to take them
when necessary,” say Younger. “We have fulltime coordination and a cadre of more than
20 Citation pilots available for this program.”
Citation customers are very satisfied with the
added convenience provided by the Mobile
Service Units to schedule routine maintenance
and also to receive unscheduled services. Even
though Mobile Service Unit procedures cost a
little more to cover the minimal expenses of
ground transportation, it is generally a less expensive outlay for the customer considering pilot time and hourly flight charges.

“I couldn’t ask for better response,” says Randy
Hunter, director of maintenance for the Chickfil-A restaurant chain. The team responds to
all customers, regardless of warranty status.
Available 18 hours a day, seven days a week including many major holidays, ART can be onsite anywhere in the continental U.S. usually
within five hours or less. ART serves the continental U.S. and parts of Mexico, Canada, Latin
America, Alaska and the Caribbean.
GO Team
Cessna’s GO Teams deliver Citation expertise
and evaluation skills to wherever an airplane
is grounded. Once the problem is diagnosed,
GO Teams from the nearest Cessna Citation
Service Centers dispatch parts and people
to quickly get Citations back in the air. And it
doesn’t have to be an AOG situation to take
advantage of a GO Team. One call dispatches
a team to respond to any maintenance need
that arises.
The cost is a simple, pre-determined labor rate
plus travel and lodging for the GO Team. It is
a bargain when compared with operational
flight cost avoidance; for example, fuel, lodging, meals, and time away from businesses for
owner/operators. Citation GO Teams all over
the world get rave reviews.
“The Citation Service Center in Paris has done
a fantastic job on my Mustang on three occasions,” says Jorgen Andersen, president and
CEO of JAI A/S. All three times the Paris-based
GO Team has traveled to Copenhagen to perform repairs.
“When I crossed the Atlantic the first time I
lost the heating system,” Andersen says. The
GO Team responded quickly, and soon had
Andersen’s Mustang ready for flight again. On
other occasions the Paris-based Cessna GO
Team replaced the AHRS1 and a Yaw servo,
both with minimal down time. “In all cases
they provided excellent support and services,”
he adds.
Contact
Cessna’s extraordinary focus on supporting only its own aircraft has led to specialized and very agile mobile services that literally go the extra mile – on land or in the
air – to keep the popular and productive
Citations flying. To learn more about the
many options available from the Cessna
Citation Service Centers call 877-303-2CSC

Randy Hunter
Director of Maintenance
ART Program Saves the Day For
Citation Operator Chick-fil-A
It’s got to be the classic nightmare for anyone who has ever gone
on a vacation. You’re just getting relaxed when the phone rings ... and
sure enough, there’s trouble at work.
For Randy Hunter, it was news that
the Cessna Citation CJ2+ he maintains
for the Chick-fil-A restaurant chain
was returning to home base with a
potentially grounding squawk. It was
already late in the day and Randy,
who is Chick-fil-A’s director of maintenance, knew the CJ2+ was scheduled
for an early morning departure with
key members of the company’s executive team on an important trip.
Eyeing the Clock
With an eye on the clock, Randy waited for the CJ2+ to land at Atlanta’s
Peachtree City-Falcon Field airport
where Chick-fil-A bases its two business aircraft, including the CJ2+ and
a mid-size jet from another manufacturer. The mid-size airplane was off
on another trip, so Randy knew he
would have to find a way to get the
CJ2+ back online before morning. Finally, the flight crew called to report
the CJ2+ was on the ground and ready
for troubleshooting.
page

Working together, Randy and the
flight crew quickly identified the
gremlin – a failed printed circuit (PC)
board in the ignition system. A call to
Cessna’s Parts Department in Wichita determined the PC board was in
stock, but it was too late in the day to
send it out by any of the normal channels. FedEx wouldn’t arrive in time to
get the airplane operational in the
morning, and the last opportunity
for a counter-to-counter airline shipment had already passed.
ART to the Rescue
An anxious Randy Hunter called Cessna Field Service Representative Dale
Witherspoon for ideas. Witherspoon
called in the Cavalry - a Cessna program called ART.
ART is short for Air Response Team.
Under the program, a Citation Ultra is
assigned to stand-by and handle AOG
problems such as Chick-fil-A’s. With a
team headed by a full-time coordinator and staffed by a rotation of flight
operations pilots and a dedicated
maintenance crew, the ART program’s
sole mission is to deliver parts, tool-
ing, technicians and technical assistance to AOG Citations and get them
back in the air.
The ART team is equipped to serve
customers anywhere in the continental United States, as well as parts of
Canada, Mexico, Alaska, Latin America
and the Caribbean. Most sites within
the U.S. served by ART can be reached
in five hours or less from the time the
team is called into action.
Routine Departure
With Dale Witherspoon facilitating
matters it was soon determined that
Chick-fil-A’s problem met the ART criteria (a time-critical AOG that could
be corrected with ART intervention)
and the Citation Ultra soon left Wichita for Atlanta carrying the critical PC
Board. A few hours later Chick-fil-A’s
CJ2+ was ready to go. When the ex-
ecutive team arrived at 8 a.m., they
were treated to a routine on-time departure.
Needless to say, Randy Hunter was
delighted. “I couldn’t ask for a better
response,” he says.
It’s not the first time Hunter has been
impressed with Cessna service. Hunter runs a hard charging operation.
Both of the airplanes he maintains
average 300 flight hours a year supporting the fast food company’s farreaching business activities.
Chick-fil-A
Chick-fil-A operates 1,430 restaurants
in 38 states and the District of Columbia. It is the second largest chicken
restaurant chain in the U.S., with
sales of more than $2.9 billion last
year. The company was founded in
1946 by Truett Cathy, who is credited
with inventing the boneless breast of
chicken sandwich.
As with many flight departments,
Hunter is the only full-time mechanic. He grew up wanting an aviation
career, and was influenced by an uncle who was a helicopter mechanic.
When Hunter graduated from high
school in his native Idaho, he enrolled in the Airframe & Powerplant
Program at the University of Idaho.
After getting his license, Hunter
moved to Atlanta to work for a
Part 135 charter operator and later
became maintenance director of
several Part 91 flight departments.
From there he was hired by Chickfil-A.
Three full-time pilots crew Chick-filA’s airplanes, assisted by COO Dan
Cathy who is type-rated in both the
CJ2+ and the company’s mid-size
jet. The larger airplane is used for
longer trips, particularly to the company’s west coast sites, although
on some trips Hunter says the company takes both aircraft so that the
entire executive team is not aboard
a single aircraft.
No Comparison
With two different aircraft makes in
his operation, Hunter has plenty of
opportunity to compare service and
support. “Customer support with the
Citation is far better,” he says. “The
field service reps with Citation are
better.”
He’s particularly proud of Cessna’s
Witherspoon. “He’s always at the hangar if we have issues, always checking on us,” Hunter says. “He’s the best
field service rep I’ve ever had.”
Hunter also cited the Citation Service
Center in Greensboro, NC. “They’ve
been particularly helpful,” he says.
“We’ve had a couple of other AOGs in
the past and they’ve been willing to
just drop everything and come down
to our hangar.”
With Cessna’s on-going commitment
to improving customer support with
innovative programs such as ART, it’s
not surprising that customers like
Randy Hunter and Chick-fil-A are happy with the results.

New Procedures Set for CJ2+ Overspeed
Warning Test
525a, ata: 34-10
There are new procedures for the Overspeed Warning Test for CJ2+ operators. “The test set airspeed values must be
increased to correctly check the CJ2+ Pitot-Static System,” says Scott Kessler, Team CJ. “The current Overspeed Warning Test procedures shown in the Maintenance Manual are for 525A-0001 thru -0299 aircraft.”
Technicians should use the following procedures for serials 525A-0300 and on:
Overspeed Warning Test
NOTE: This test is not necessary by Title 14 CFR, but it has to be done for continued airworthiness.
A. Complete an Overspeed Warning Test
(1) Engage AUDIO 1 and AUDIO 2 circuit breakers on the right circuit breaker panel, and the WARNING LANDING
GEAR circuit breaker on the left circuit breaker panel.
(2) On the test set, increase the static pressure to provide an altitude of 30,000 feet (9144 meters), and allow it
to stabilize for five minutes minimum.
(3) On the test set, set the airspeed to 278 knots (515 km/hr).
(4) On the test set, increase the airspeed at a rate of 20 knots (37 km/hr) or less.
(a) Make sure you hear the overspeed alert tone when 280 to 283 knots (519 to 524 km/hr) is shown on the PFD 1, PFD 2, and SFD.
(b) Make sure you see the overspeed red band at the top of the Airspeed Display on the PFD 1, PFD 2, and SFD, when 280 to 283 knots (519 to 524 km/hr) is shown on the PFD 1, PFD 2, and SFD.
(5) On the test set, decrease the airspeed to 268 knots (496 km/hr).
(a) Make sure you do not hear the overspeed alert tone.
(b) Make sure you do not see the overspeed red band at the top of the Airspeed Display on the PFD 1, PFD 2, and SFD.
Team CJ has submitted a Technical Publication Change Request to revise the Model 525A Maintenance Manual in
Chapter 34, Pitot-Static System – Inspection/Check. Operators should expect to see the new procedures in an upcoming revision to the manual.

Weight and Balance Manual Transition
all models, ata: 99-00
In March 2008, the Citation X Weight and Balance Manual (75WBM) Revision 03 was
released affecting 750 -0173 and on, as well as, units -0001 through -0172 incorporating
SB750-32-50 or SB750-71-10. Among the changes, a transition in specific fuel density from
6.75 lbs/gal to 6.70 lbs/gal was included.
This manual also utilizes a newer, more accurate fuel load model. When the revision
released, all customers with the Citation Loading Calculator (CLCalc) were issued new
databases which reflected the changed fuel tables. Unfortunately, the fuel tables in the
Airplane Flight Manuals (AFM) were not updated since these pages are serial-specific and
not part of the revision service. The altered fuel density resulted in a moment shift of
the fuel tables and a reduction of nearly 100 lbs of usable fuel. Recently, two of our Citation X operators discovered the discrepancy between the AFM, WBM and CLCalc. The two
main points of concern were: the pilots were not receiving Weight and Balance Manual
updates, and the WBM is the only source of information for updating the serial-specific
pages found in Section VI of the AFM.
To resolve the issue outlined in the first paragraph, Cessna has added a single WBM
subscription service at no charge in addition to the AFM and Checklist revision services
already setup for each aircraft serial number. AFM revision services that are not associated with an aircraft are not included in this addition, and WBM revision services can be
purchased separately. The initial manuals will be mailed third quarter 2009. These documents are FAA-Approved and will be required to be on-board the aircraft; we suggest they
be inserted in the AFM if space permits. This action will be taken on all Citations with the
exception of the CJ series. These aircraft do not have a separate WBM as the info is in the
AFM. Citation Mustangs already include a WBM subscription.

2. Product Improvements – ideas for improvements to products or procedures.
3. Technical Publications Discrepancies – errors or typos in maintenance or operation publications.
Issues Not Recommended for SCRs
SCRs should not be used to report scheduled and unscheduled removals unless they fall into one of the categories
above. CESCOM Maintenance Transaction Reports (MTRs) are
the correct reporting methods for these types of situations.
Customers with an immediate need or an AOG aircraft should
not utilize the SCR form as they are not reviewed daily. Customers in this category should call a Field Service Representative or the Customer Service Hotline.

The Federal Aviation Administration (FAA) has issued a Safety Alert for Operators
regarding in-flight fires caused by laptop computers. SAFO 09013 provides guidance on
safely extinguishing fires caused by lithium/lithium-ion cell batteries used in laptop
computers.
The document was created because laptop computer batteries may malfunction and
overheat, often during a charging process. The over-temperature condition can cause
the battery pack to catch fire.
Laptop computer hazards consist of battery packs, which commonly contain six to nine
battery cells. The lithium/lithium-ion cells become dangerous when the internal temperature reaches 350° F in a thermal runaway condition. A battery cell in such a state will get
extremely hot, then overpressure, releasing a flammable liquid electrolyte. Other cells in
the battery pack that have overheated can cause multiple explosions and fire after the
initial fire has been extinguished.
The FAA document warns that there should be no attempt to pick-up and move the computer, as there is extreme danger of bodily harm. Passengers should be moved away from
the malfunctioning device.
Recommended procedures for an in-flight laptop computer fire are:
1. Use a portable fire extinguisher to extinguish the fire and prevent the spread of flames
to additional flammable materials.
2. Douse the device generously with water or other non-alcoholic liquids to cool the battery pack in order to prevent additional cells from reaching thermal runaway temperatures.
3. Don’t cover or use ice to cool the device. Ice or other materials work to insulate the
battery pack, significantly increasing the potential of additional battery cells reaching
thermal runaway temperatures after the fire has been extinguished.
The FAA has developed a training video to demonstrate effective techniques for fighting
lithium/lithium-ion battery fires. The video entitled “Extinguishing In-Flight Laptop Computer Fires” can be viewed using the link below and clicking on the “Training Videos” link

Cessna Approves LEDs for Emergency
Over-Wing Lights
525, 525a, 525b, ata: 33-40
Cessna Engineering has approved use of Light Emitting Diode (LED) lights as direct replacement parts
for existing emergency over-wing lights. Operators can order the new lights from Citation Parts Distribution
(CPD) using P/N OWL100-03 as a substitute for the older P/N 30-1767-1 incandescent light bulbs. Please call
CPD for more information at 1-877-CPD-5882 (1-877-273-5882).
The new LED lighting fixtures arrive with positive and negative electrical lead wires which can be spliced into
the existing wiring using standard wiring maintenance procedures.

Maintenance Tip Suggested to Avoid
Stripped Threads
525, 525a, 525b, ata: 73-30
This is a reminder to technicians when installing or tightening B-nuts on
fuel line tube assemblies to use two wrenches. One wrench should be used to
restrain the union from turning while using the second wrench to tighten the
related B-nut.
Citation Customer Service and Williams-International have received reports
concerning stripped threads of the engine FJ44 Fuel Delivery Unit (FDU) on FADEC controlled engines on CJ1+, CJ2+, and CJ3 aircraft.
– YOUR CONTACT –
A non-restrained union can turn when B-nuts are torqued during installation of
fuel lines potentially damaging or stripping threads in the FDU.

Team X Answers Nose Wheel
Steering Questions
750, ata: 32-50
Team X has received reports regarding the nose tiller wheel not automatically centering. Some flight crews have
also questioned why the nose tiller
wheel does not mechanically center itself during ground taxi operations?
The answer is…the Citation X nose wheel
steering design was developed with a
tiller wheel centering assist mechanism.
The system was not designed to center
the tiller wheel on its own because if a
turn was commanded and the pilot’s
page
13
hand slips on the tiller wheel it could
cause an inadvertent and undesirable
turn back to center.
Depending upon the airplane serial effectivity, the tiller wheel uses a centering assist spring or bungee to ease the
amount of force required by the pilot to
center the tiller wheel.

experts from the cessna support team
share advice and shed light
We replaced the wheel assembly
on our CJ3. The tire has moved three
inches on the rim after seventeen
landings. We cannot find any reference to the status of the wheel assembly in the vendor publications.
Can you please provide assistance?
Answer
We contacted both wheel and tire manufacturers on this subject. From the
manufacturer representatives we were
told the following:
Tire creep is acceptable with less
than 1 inch of movement on the
wheel. However, tire slippage is not
acceptable with more than 1 inch
of movement. Probable causes can
be under inflation of the tire, improper tire seating during build-up, a
wheel flange out of specifications, a
tire bead out of specification, or too
much lubrication used to install the
tire.
Cessna recommends disassembling
and inspecting the wheel and tire assemly per the wheel manufacturer’s

In addition, make sure the tire and
wheel mating surfaces are clean prior to tire installation.
