AD 2015-13-02 Airworthiness Directives; Bombardier, Inc. Airplanes
Models named: DHC-8-400, -401, -402. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Bombardier, Inc. Model DHC-8-400, -401, and -402 airplanes, certificated in any category, serial numbers 4001 through 4424 inclusive.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD, perform an inspection (integrity check) for leakage of the fire protection tube assemblies of the forward baggage compartment, in accordance with paragraph 3.B., “Procedure,” of Part A of the Accomplishment Instructions of Bombardier Service Bulletin 84-26-15, Revision A, dated January 15, 2014. If no leakage is found, repeat the inspection at intervals not to exceed 2,000 flight hours or 12 months, whichever occurs first. If any leakage is found, before further flight, do the terminating action required by paragraph (h) of this AD, except as provided by paragraph (i) of this AD. (1) For airplanes that have accumulated 10,000 total flight hours or more, or have been in service for 60 months or more as of the effective date of this AD: Within 2,000 flight hours or 12 months after the effective date of this AD, whichever occurs first. (2) For airplanes that have accumulated less than 10,000 total flight hours, and have been in service for less than 60 months, as of the effective date of this AD: Before the accumulation of 12,000 total flight hours or 72 months in service, whichever occurs first.
Unsafe condition
This AD was prompted by reports of corrosion in the low-rate discharge tubes of the fire protection system leading to the forward baggage compartment, and perforation of one or more tubes. We are issuing this AD to prevent perforation of the low-rate discharge tubes, which could result in insufficient fire extinguishing agent reaching the forward baggage compartment in the event of a fire, which could result in damage to the airplane and injury to the occupants.
Affected ADs
None.
