Who is responsible for
Airworthiness?
•
•
•
•
This is a shared responsibility.
The pilot is ultimately responsible!
As a pilot, you need to understand this.
As a flight instructor, you need to make
sure that your students understand this.
• Operating rules prohibit the operation of
an aircraft that is not airworthy.
91.3 Responsibility and authority
of the pilot in command.
• (a) The pilot in command of an aircraft is
directly responsible for, and is the final
authority as to, the operation of that
aircraft.
91.7 Civil Aircraft Airworthiness
• (a) No person may operate a civil aircraft
unless it is in an airworthy condition.
• (b) The pilot in command of a civil aircraft
is responsible for determining whether that
aircraft is in condition for safe flight. The
pilot in command shall discontinue the
flight when unairworthy mechanical,
electrical, or structural conditions occur.
91.403 General.
• (a) The owner or operator of an aircraft is primarily
responsible for maintaining that aircraft in an airworthy
condition, including compliance with part 39 of this chapter.
• (b) No person may perform maintenance, preventive
maintenance, or alterations on an aircraft other than as
prescribed in this subpart and other applicable regulations,
including part 43 of this chapter.
• (c) No person may operate an aircraft for which a
manufacturer's maintenance manual or instructions for
continued airworthiness has been issued that contains an
airworthiness limitations section unless the mandatory
replacement times, inspection intervals, and related
procedures specified in that section or alternative inspection
intervals and related procedures set forth in an operations
specification approved by the Administrator under part 121 or
135 of this chapter or in accordance with an inspection
program approved under §91.409(e) have been complied
with.
91.405 Maintenance required.
• Each owner or operator of an aircraft—
• (a) Shall have that aircraft inspected as prescribed in subpart E
of this part and shall between required inspections, except as
provided in paragraph (c) of this section, have discrepancies
repaired as prescribed in part 43 of this chapter;
• (b) Shall ensure that maintenance personnel make appropriate
entries in the aircraft maintenance records indicating the aircraft
has been approved for return to service;
• (c) Shall have any inoperative instrument or item of equipment,
permitted to be inoperative by §91.213(d)(2) of this part,
repaired, replaced, removed, or inspected at the next required
inspection; and
• (d) When listed discrepancies include inoperative instruments or
equipment, shall ensure that a placard has been installed as
required by §43.11 of this chapter.
91.407 Operation after maintenance,
preventive maintenance, rebuilding, or
alteration.
•
•
•
•
•
(a) No person may operate any aircraft that has undergone
maintenance, preventive maintenance, rebuilding, or alteration unless—
(1) It has been approved for return to service by a person authorized
under §43.7 of this chapter; and
(2) The maintenance record entry required by §43.9 or §43.11, as
applicable, of this chapter has been made.
(b) No person may carry any person (other than crewmembers) in an
aircraft that has been maintained, rebuilt, or altered in a manner that
may have appreciably changed its flight characteristics or substantially
affected its operation in flight until an appropriately rated pilot with at
least a private pilot certificate flies the aircraft, makes an operational
check of the maintenance performed or alteration made, and logs the
flight in the aircraft records.
(c) The aircraft does not have to be flown as required by paragraph (b)
of this section if, prior to flight, ground tests, inspection, or both show
conclusively that the maintenance, preventive maintenance, rebuilding,
or alteration has not appreciably changed the flight characteristics or
substantially affected the flight operation of the aircraft.
Responsibility may be shared,
MAYBE.
• Depending on who you’re working for, you
may have a partner in the responsibility for
airworthiness.
• Shared responsibility is limited.
• You are ultimately responsible for the
condition of the aircraft that you operate.
• Will your partner stand up for you?
• Choose your partners carefully.
43.5 Approval for return to service after
maintenance, preventive maintenance,
rebuilding, or alteration.
• No person may approve for return to service any aircraft, airframe,
aircraft engine, propeller, or appliance, that has undergone
maintenance, preventive maintenance, rebuilding, or alteration
unless—
• (a) The maintenance record entry required by §43.9 or §43.11, as
appropriate, has been made;
• (b) The repair or alteration form authorized by or furnished by the
Administrator has been executed in a manner prescribed by the
Administrator; and
• (c) If a repair or an alteration results in any change in the aircraft
operating limitations or flight data contained in the approved aircraft
flight manual, those operating limitations or flight data are
appropriately revised and set forth as prescribed in §91.9 of this
chapter.
14 CFR 141.39 Aircraft.
•
•
•
•
•
•
An applicant for a pilot school certificate or provisional pilot school certificate
must show that each aircraft used by that school for flight training and solo
flights meets the following requirements:
(a) Each aircraft must be registered as a civil aircraft in the United States;
(b) Each aircraft must be certificated with a standard airworthiness
certificate or a primary airworthiness certificate, unless the Administrator
determines that due to the nature of the approved course, an aircraft not
having a standard airworthiness certificate or primary airworthiness
certificate may be used;
(c) Each aircraft must be maintained and inspected in accordance with
the requirements under subpart E of part 91 of this chapter that apply to
aircraft operated for hire;
(d) Each aircraft used in flight training must have at least two pilot stations
with engine-power controls that can be easily reached and operated in a
normal manner from both pilot stations; and
(e) Each aircraft used in a course involving IFR en route operations and
instrument approaches must be equipped and maintained for IFR
operations. For training in the control and precision maneuvering of an
aircraft by reference to instruments, the aircraft may be equipped as
provided in the approved course of training.
Airworthiness Defined
Two conditions must be met before an aircraft can be
considered “airworthy”:
• The aircraft must conform to its type certificate (TC);
that is, when the aircraft configuration and the
components installed are consistent with the drawing,
specifications, and other data that are part of the TC,
and include any supplemental TC and field-approved
alterations incorporated into the aircraft.
• The aircraft must be in condition for safe operation;
this refers to the condition of the aircraft relative to
wear and deterioration.
AIRWORTHY MEANS AN AIRCRAFT MEETS ITS TYPE
DESIGN AND IS IN A CONDITION FOR SAFE OPERATION.
THIS DEFINITION IS TAKEN FROM PUBLIC LAW 103-272,
PREVIOUSLY THE FEDERAL AVIATION ACT OF 1958, AND IS
ALSO FOUND ON THE FACE OF EACH AIRCRAFT'S
STANDARD AIRWORTHINESS CERTIFICATE.

What is a repair?
• A repair restores the aircraft to its’ original
unaltered or properly altered condition.
• Repairs must be accomplished in
accordance with the manufacturer’s
maintenance instructions or standard
practices acceptable to the Administrator.
• Major repairs must be accomplished in
accordance with approved data.
Major vs. Minor Repair
Major Repair. A repair that fits one or more of the
following:
• (1) Might appreciably affect airworthiness by
changing weight, balance, structural strength,
performance, powerplant operation, or flight
characteristics if improperly done; or
• (2) Is not done according to accepted practices or
cannot be done by elementary operations.
Minor Repair. Any repair that is not classified as a
major repair.
MAJOR REPAIRS AND MAJOR ALTERATIONS
Major Repair means a repair:
That, if improperly done, might appreciably
affect weight, balance, structural strength,
performance, powerplant operation, flight
characteristics, or other qualities affecting
airworthiness; or
That is not done according to accepted
practices or cannot be done by elementary

The Grey Area
• Manufacturer’s maintenance instructions
may be limited in content and detail.
• Individual interpretation or understanding
of the term “airworthy” may vary.
• You may consider the aircraft to be safe,
but does it qualify as airworthy?
• Use your resources. Ask questions.
• Always be in a defendable position.
What to look for:
• Verify that scheduled maintenance
requirements are current.
• Verify that there are no open
discrepancies (unscheduled).
• Verify that maintenance record entries
have been made.
• Do a good preflight.
Scheduled Maintenance
•
•
•
•
•
•
•
Required inspections (annual/100 hr.)
Replacement of life limited components
Altimeter/Transponder Certifications
ELT battery replacement
ELT annual check
Airworthiness Directives
All of these are predictable
Flying Clubs
Legal Interpretation # 2000-2
• If a student furnishes an airplane which is
not operated for hire and he/she hires the
flight instructor, there is no requirement to
accomplish 100 hour inspections.
• 100 hour inspections are required if you
provide flight instruction for hire and also
provide the aircraft.
Unscheduled Maintenance
