Airworthiness Directive 2010-33336

AD 2010-33336 · 2011-01-10 · airframe

Airworthiness Directives; Cessna Aircraft Company (Cessna) (Type Certificate A00003SE Previously Held by Columbia Aircraft Manufacturing (Previously The Lancair Company)) Models LC41-550FG and LC42-550FG Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for the products listed above. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires obtaining written approval from the Manager, Wichita Aircraft Certification Office (ACO), to operate the airplane. This written approval must clearly state that operation is approved per Emergency AD 2010-26-54. This AD was prompted by a Cessna Model LC41-550FG airplane that suffered a significant structural failure in the wing during a production acceptance flight test. We are issuing this AD to prevent catastrophic failure of the wing due to disbonding of the wing skin from the wing spar.

Whether AD 2010-33336 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 2010-33336 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.
