## The airworthiness directive

60-03-05 LOCKHEED: Amdt. 95 Part 507 Federal Register February 2, 1960. Applies to All Model L-188 Aircraft.

Compliance required by April 1, 1960.

Loss of the top cowl panel over the engine tail pipe has occurred in flight due to insecurity of the cowl latches. To prevent recurrence of this difficulty, the following modifications must be accomplished:

  (a) Modify latch assemblies by replacement of snap ring retention with clevis or shoulder pin design and safety in place.

  (b) Install position pins and locators to provide more positive alinement of the cowling with the latches when in the closed position.

(Lockheed Service Bulletins Nos. 188/295 and 188/365 cover this same subject.)
