Applicability (c) This AD applies to the following airplane models and serial numbers (SNs) that are certificated in any category: (1) Group 1 (maintains the actions from AD 72-22-01): Model SNs (i) 35-33, 35-A33, 35-B33, 35-C33, E33, F33, and G33 CD-1 through CD-1256 (ii) 35-C33A, E33A, and F33A CE-1 through CE-349 (iii) E33C and F33C CJ-1 through CJ-30 (iv) 35, A35, B35, C35, D35, E35, F35, G35, H35, J35, K35, M35, N35, P35, S35, V35, V35A, and V35B D-1 through D-9287 (v) 36 and A36 E1 through E-283 (vi) A45 (T-34A, B45) and D45 (T-34B) All (vii) 95-55, 95-A55, 95-B55, and 95-B55A TC-1 through TC-1402 (viii) 95-C55, 95-C55A, D55, D55A, E55, and E55A TE-1 through TE-846 (ix) 56TC and A56TC TG-1 through TG-94 (x) 58 TH-1 through TH-174 (xi) 95, B95, B95A, D95A, and E95 TD-2 through TD-721 (2) Group 2: Model 95-B55B (T-42A) airplanes, SNs TF-1 through TF-70. Unsafe Condition (d) This AD results from a recent incident involving a Raytheon Aircraft Company (RAC) Model 95-B55B (T-42A) airplane where a seizure of the uplock rollers occurred. We are issuing this AD to decrease the possibility of gear-up landings caused by seizure of the uplock rollers. Compliance (e) To address this problem, you must do the following, unless already done: Actions Compliance Procedures (1) Determine if each uplock roller is of the greasible type (one having a drilled and grooved inner race). (i) For Group 1 airplanes: Within 300 hours time-in-service (TIS) after October 25, 1972 (the effective date of AD 72-22-01). (ii) For Group 2 airplanes: Within 300 hours TIS after May 25, 2007 (the effective date of this AD). Follow Beechcraft Service Instructions No. 0448-211, Rev. I (undated), or Beechcraft Service Instructions No. 0448-211 (undated). (2) Replace any nongreasible uplock roller (one having a solid inner race) with the greasible type. (i) For Group 1 airplanes: Before further flight after the determination required by paragraph (e)(1)(i) of this AD. (ii) For Group 2 airplanes: Before further flight after the determination required by paragraph (e)(1)(ii) of this AD. Follow Beechcraft Service Instructions No. 0448-211, Rev. I (undated), or Beechcraft Service Instructions No. 0448-211 (undated). (3) Install hollow zerk-ended mounting bolts on the uplock rollers. (i) For Group 1 airplanes: Within 300 hours TIS after October 25, 1972 (the effective date of AD 72-22-01). (ii) For Group 2 airplanes: Within 300 hours TIS after May 25, 2007 (the effective date of this AD). Follow Beechcraft Service Instructions No. 0448-211, Rev. I (undated), or Beechcraft Service Instructions No. 0448-211 (undated). (4) Lubricate the uplock mechanism. (i) For Group 1 airplanes: Initially within 300 hours TIS after October 25, 1972 (the effective date of AD 72-22-01). Repetitively lubricate thereafter at intervals not to exceed 100 hours TIS. (ii) For Group 2 airplanes: Initially within 300 hours TIS after May 25, 2007 the effective date of this AD. Repetitively lubricate thereafter at intervals not to exceed 100 hours TIS. Follow Beechcraft Service Instructions No. 0448-211, Rev. I (undated), or Beechcraft Service Instructions No. 0448-211 (undated).
