Airworthiness Directives; Cessna Model 750 Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Cessna Model 750 airplanes. This action requires repetitive lubrication of the aileron feel cartridge assembly shaft. This action also requires replacement of the roll feel and centering bungee assembly with an improved assembly, which constitutes terminating action for the repetitive lubrication. This amendment is prompted by reports of partial to full jamming of the aileron control circuit during flight of the airplane. The actions specified in this AD are intended to prevent the possibility of accumulation of ice on the aileron feel cartridge assembly shaft, which could result in jamming of the aileron control circuit, and consequent reduced controllability of the airplane.

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.

Specific model not independently confirmed in provided applicability text (bulletin numbers ASL750-12-02 / SB 750-27-10 suggest a Cessna Citation Model 750, per Cessna's standard model-first bulletin numbering, but this is not stated in prose in the given text). Within 10 hours TIS after effective date, lubricate the aileron feel cartridge assembly shaft per Cessna Citation Alert SL ASL750-12-02 (Sept 29, 1997); repeat every 30 days until the paragraph (b) replacement is done. Within 60 days after effective date, replace the roll feel centering bungee assembly with an improved assembly per Cessna Citation SB 750-27-10 (Jan 16, 1998, incl. Supplemental Data); this replacement terminates the repetitive lubrication requirement (and is not required if already done within the 10-hour window). Prevents ice accumulation on the aileron feel cartridge shaft causing possible aileron control jamming.

Whether AD 98-05-02 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 98-05-02 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.
