Airworthiness Directive · Amendment 39-18164 · Flight controls
Slingsby Aviation Ltd. Airplanes
Superseded. A later AD replaced this one: AD 2017-10-02. Comply with the one in force.
This AD applies to Slingsby Aviation Ltd. Models T67M260 and T67M260-T3A airplanes, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for Slingsby Aviation Ltd. Models T67M260 and T67M260-T3A airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as failure of a brake master cylinder pivot pin. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the actions in paragraphs (f)(1) and (f)(2) of this AD.
(1) Before further flight after June 16, 2015 (the effective date of this AD) and repetitively thereafter every 300 hours time-in-service or 12 months, whichever occurs first, inspect the brake master cylinder pivot pins, part number T67M-45-539, installed on rudder pedal assemblies #1 and #4. Do the inspections following the Accomplishment Instructions in Marshall Aerospace and Defence Group Service Bulletin SBM 200, Revision 1, dated April 2015. This AD does not require the retention and reporting requirements of paragraph (2) of F. COMPLETION in the Accomplishment Instructions of this service bulletin.
(2) If, during any inspection required in paragraph (f)(1) of this AD, any crack or distortion to a brake master cylinder pivot pin is found, or a pivot pin fails the dimensional check, before further flight, replace the affected pivot pin with a serviceable part. Do the replacement as specified in paragraph C.(1)(j) of the Inspection section of the Accomplishment Instructions in Marshall Aerospace and Defence Group Service Bulletin SBM 200, Revision 1, dated April 2015. After doing this replacement, continue with the repetitive inspection requirement in paragraph (f)(1) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
