FLIGHT CREW OPERATIONS SUMMARY
This summary provides additional information for the flight crew regarding operational changes as a result
of accomplishment of this service bulletin. Please remove this summary from the service bulletin and give
it to the flight crew. This summary is informational only and does not supersede any information in the
FAA Approved Airplane Flight Manual.
•
The completion of Pratt & Whitney Canada Service Bulletin PW500-72-30290 will correct the flameout
condition that occurs when the engine is decelerated below 70% N2.
•
The transition from electronic engine control mode to manual mode causes a sudden drop in fuel pressure.
•
The drop in pressure causes the fuel pressure to be less than the deceleration minimum fuel flow limit.
•
The new hydromechanical fuel control unit has improved internal sealing which eliminates the pressure
drop when transitioning between auto and manual modes.

Summary:
CATEGORY 5
There can be an engine flame out in the operation range of 60% to 70% N2 (High
Pressure Compressor Rotor Speed) during the transfer from the engine electronic
control mode to the manual mode. This is because of a sudden drop of the fuel flow
below the minimum deceleration flow limit. Replace the HFC unit with a new one
that has a better fuel flow deceleration.

An upgrade exchange price of $18,000* is offered for FCU with up to 2,500 hours
where the FCU is exchanged for the purpose of incorporating the modifications.
An upgrade exchange price of $25,000* is offered for FCU with up to 5,000 hours
where the FCU is exchanged for the purpose of incorporating the modifications.
Price is pro-rated between 2,500 – 5, 000 hours using the following formula:
Price = $18,000* +($2.80* x (FCU total time – 2,500)), to a maximum of
$25,000*. ( if FCU total time is not available, consider it is above 5000 hrs).
