Is AD 2010-33345 a recurring Airworthiness Directive?

No — AD 2010-33345 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2010-33345 apply to?

AD 2010-33345 applies to Boeing — models DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), MD-88, DC-9. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires installing fuel level float and pressure switch in-line fuses on the wing forward spars and forward and aft auxiliary fuel tanks, depending on the airplane configuration. This AD was prompted by fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

Applies only to airplanes identified in Boeing Service Bulletin MD80-28-226, dated April 14, 2010. Note 1 further limits applicability to airplanes on which switches are installed per McDonnell Douglas MD-80 Service Bulletin 28-054 (dated April 8, 1991, or Revision 1 dated April 15, 1992) or MD-80 Service Bulletin 28-058 (dated April 8, 1991, Revision 1 dated August 2, 1991, or Revision 2 dated July 6, 1992), or production equivalent.

Whether AD 2010-33345 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.
