Models named: BD-100-1A10. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, serial numbers (S/Ns) 20003 through 20500 inclusive and 20501 through 20696 inclusive.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 30 months after the effective date of this AD: Modify the APU electronic control unit (ECU) wiring harness, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 100-49-04, dated March 29, 2017 (for S/N 20003 through 20500 inclusive); or Bombardier Service Bulletin 350-49-001, dated March 29, 2017 (for S/N 20501 through 20696 inclusive).

Unsafe condition

This AD was prompted by reports of fire incidents of the auxiliary power unit (APU) inlet, which caused tail cone damage after an initial failed APU start followed by two or more in-flight APU start attempts. We are issuing this AD to prevent failure of the APU inlet, which could result in a fire during flight.

Affected ADs

None.
