Airworthiness Directive 00-20649
one-timeAirworthiness Directives; Bombardier Model DHC-7-100, and DHC-8-100, -200, and -300 Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to all Bombardier Model DHC-7-100, and DHC-8-100, -200, and -300 series airplanes, that requires a one-time inspection of maintenance records to determine the method used during the most recent weight and balance check of the airplane and, if necessary, accomplishment of a weight and balance check. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent unusual handling characteristics and consequent reduced controllability during ground operations due to incorrect methods of weighing and balancing the airplane.
Which aircraft AD 00-20649 applies to
applicability derived from the AD summary — confirm the model/serial from the records
Whether AD 00-20649 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.
