Is AD 2010-13-08 a recurring Airworthiness Directive?

Yes — AD 2010-13-08 requires a repetitive inspection every 1200 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2010-13-08 apply to?

AD 2010-13-08 applies to Air Tractor, Inc. — models AT-802, AT-802A. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Air Tractor, Inc. Models AT-802 and AT-802A Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) to supersede AD 2006-08-09, which applies to all Air Tractor, Inc. (Air Tractor) Models AT-802 and AT-802A airplanes. AD 2006-08-09 currently requires you to repetitively inspect (using the eddy current method) the two outboard fastener holes in both of the wing main spar lower caps at the center splice joint for cracks and repair or replace any cracked spar cap. Since we issued AD 2006-08-09, we have determined we need to clarify the serial numbers (SNs) of the Models AT-802 and AT- 802A airplanes affected by that AD. Additionally, we are adding an option of modifying the wing main spar lower caps to extend the safe life limit on the affected airplanes. Consequently, this AD would keep the actions of AD 2006-08-09, clarify the affected SNs, and add a modification option to extend the safe life limit. We are issuing this AD to detect and correct cracks in the wing main spar lower cap at the center splice joint, which could result in failure of the spar cap and lead to wing separation and loss of control of the airplane.

Repetitive inspection. Re-inspect every 1200 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — 80540.

Applies to all serial numbers beginning with -0001, when: certificated in any category; engaged in (or convertible to/from) agricultural dispersal operations; NOT equipped with factory-supplied computerized fire gate P/N 80540; and NOT engaged in only full-time fire fighting.

Whether AD 2010-13-08 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
