AD 2024-18-04 Airworthiness Directives; Bombardier, Inc., Airplanes
Models named: BD-700-2A12. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Bombardier, Inc., Model BD-700-2A12 airplanes, certificated in any category, serial numbers 70006 through 70166 inclusive.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 1,500 flight hours or 3 years, whichever occurs first after the effective date of this AD, replace TRU Number 2 part number (P/N) G02404521-001 with P/N G02404521-003, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 700-24-7507, Revision 2, dated October 16, 2023.
Unsafe condition
This AD was prompted by a report that the fan in a transformer rectifier unit (TRU) can become inoperative in a manner that is not detectable by the fan monitoring circuit. The FAA is issuing this AD to address the inability of a TRU to detect the fan failure. The unsafe condition, if not addressed, could lead to overheating and failures on the remaining TRUs, which could contribute to additional pilot workload and adversely affect the safe operation of the airplane.
Affected ADs
None.
