AD 98-24-25 Airworthiness Directives; Lockheed Model L-188A and L-188C Series Airplanes

Models named: L-188A, L-188C series. Read the applicability below — it usually turns on serial or part numbers too.

All Model L-188A and L-188C series airplanes, certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Required as indicated, unless accomplished previously. To prevent undetected accretion of ice on the horizontal stabilizer, which could result in ice contaminated tailplane stall and consequent loss of pitch control, accomplish the following: [[Page 65046]] (a) Within 30 days after the effective date of this AD, revise the Limitations, Normal Procedures, and Performance Sections and Appendix III of the FAA-approved Electra 188A or 188C Airplane Flight Manual (AFM), as applicable, to include the pages specified in Table 1 (for Model L-188A series airplanes), Table 2 (for Model L-188C series airplanes not equipped with Hamilton Standard propellers), or Table 3 (for Model L-188C series airplanes equipped with Hamilton Standard propellers) of this AD, as applicable.
