AD: Hamilton Sundstrand Power Systems

AD NUMBER: 2009-21-03

MANUFACTURER: Hamilton Sundstrand Power Systems T- 62T-46C12 Auxiliary Power Units
SUBJECT: Airworthiness Directive 2009-21-03

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Hamilton Sundstrand Power Systems T-62T-46C12 auxiliary power units (APUs). This AD requires upgrading the software in the APU full- authority digital controller (FADEC) from software version 02.01.000 to version 03.00.000. This AD results from two reports of APU compartment explosions due to over-fueling of the APU at low revolutions-per-minute during the start sequence. We are issuing this AD to prevent over- fueling of the APU during the start sequence, which could lead to fuel explosions, injury, and damage to the APU and the airplane.
