Airworthiness Directives; Cessna Model 500, 501, 550, and 551 Airplanes

What this AD requires

This document corrects information in an existing airworthiness directive (AD) that applies to certain Cessna Model 500, 501, 550, and 551 airplanes. That AD currently requires a one-time inspection of the brake stator disks to determine to what change level they have been modified (if any), and related investigative and corrective actions if necessary. That AD also requires that the existing markings on the piston housing of certain brake assemblies be eliminated. This document corrects the compliance time for the inspection for cracked or broken stator disks on certain airplanes. This correction is necessary to ensure that affected airplanes are given sufficient time to comply with the requirements of this AD.

Which aircraft AD 2004-09-05 applies to

Applicability depends on the aircraft’s type certificate — check it against the specific tail.

Whether AD 2004-09-05 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 2004-09-05 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.
