Airworthiness Directives; Thrush Aircraft, Inc. Model 600 S2D and S2R (S-2R) Series Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) to supersede AD 2003-07-01, which applies to certain Thrush Aircraft, Inc. Model 600 S2D and S2R (S-2R) series airplanes (type certificate previously held by Quality Aerospace, Inc. and Ayres Corporation). AD 2003-07-01 currently requires you to repetitively inspect the \1/4\- inch and \5/16\-inch bolt hole areas on the lower wing spar caps for fatigue cracking; replace or repair any lower wing spar cap where fatigue cracking is found; and report any fatigue cracking found. This AD is the result of the analysis of data from 112 cracks found in the last 8 years on similar design Model 600 S2D and S2R (S-2R) series airplanes, and FAA's determination that an immediate initial inspection and more frequent repetitive inspections are necessary to address the unsafe condition for certain airplanes. Consequently, this AD would require you to increase the frequency of the repetitive inspections on Groups 1, 2, 3, and 6 airplanes; and decrease the hours time-in-service (TIS) for the initial inspection on Group 2 airplanes. We are issuing this AD to prevent lower wing spar cap failure caused by undetected fatigue cracks. Such failure could result in loss of a wing with consequent loss of airplane control.

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

Whether AD 06-3162 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.
Is AD 06-3162 complied with on your aircraft?

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.
