Airworthiness Directive 2007-02-04
one-timeAirworthiness Directives; SOCATA-Groupe Aerospatiale TB 20 and TB 21 Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as reports of interference between the wing spar lower boom and the wheel fairing attaching screw. We are issuing this AD to require actions to correct the unsafe condition on these products.
Which aircraft AD 2007-02-04 applies to
Excludes airplanes with repair REP 20.031 implemented on both sides.
Whether AD 2007-02-04 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.
