Airworthiness Directive 2016-17-16
one-timeAirworthiness Directives; Bombardier, Inc. Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by in-service reports of passenger door tensator spring failures, and qualification testing indicating that non-conforming tensator springs could be susceptible to failure prior to reaching their safe-life limit. This AD requires revising the maintenance or inspection program to incorporate certain temporary revisions, and replacing the passenger door tensator springs with new springs. We are issuing this AD to prevent tensator spring failure, resulting in the inability to open the main passenger door, which could impede evacuation in the event of an emergency.
Which aircraft AD 2016-17-16 applies to
Applies to serial numbers 9002 and subsequent.
Whether AD 2016-17-16 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
