FATIGUE LIFE LIMITS ON THE L'HOTELLIER COUPLING BALLS IN THE AIRBRAKE CIRCUIT
Applicable to the Standard Cirrus, all variants, all serial numbers. This AD was originally issued in 1979; however the original AD did not make it clear that the balls must be replaced every 500 hours and not just after the first 500 hours. The original AD also quoted an incorrect part number for the replacement ball; this is corrected in this Issue. The replacement ball design has been modified by the manufacturer. The thread length is now slightly shorter and begins 2.5 mm below the flange. It is necessary to relieve the bellcrank hole to allow the flange to sit flat on the bellcrank surface. Note: The general servicing requirement of AD 177 must be complied with. Schempp-Hirth Technical Note 278-23 refers.
