AD FAA-2006-26075

We are adopting a new airworthiness directive (AD) that supersedes AD 72-22-01, which applies to certain Raytheon Aircraft Company (RAC) (The Beech Aircraft Company and BEECH previously held Type Certificate Nos. 3A15, 3A16, 5A3, and A-777) Models 33, 35, 36, 45, and 95 series airplanes. AD 72-22-01 currently requires you to determine if each uplock roller is of the greasible type (one having a drilled and grooved inner race), replace any nongreasible uplock roller (one having a solid inner race) with the greasible type before further flight, install hollow zerk-ended mounting bolts on the uplock rollers, and repetitively lubricate the uplock mechanism. Since we issued AD 72- 22-01, there was a recent incident involving a RAC Model 95-B55B (T- 42A) airplane where a seizure of the uplock rollers occurred. This malfunction of the uplock rollers is addressed in AD 72-22-01. Thus, the FAA has determined that the actions of AD 72-22-01 should also apply to certain serial numbers of the Model 95-B55B (T-42A) airplanes. Consequently, this AD retains all the actions of AD 72-22-01, adds those Model 95-B55B (T-42A) airplanes to the applicability of this AD, and lists the specific serial numbers. We are issuing this AD to decrease the possibility of gear-up landings caused by seizure of the uplock rollers.
