Compliance required as indicated, unless previously accomplished.

To ensure the integrity of the cowl door latches, accomplish the following:

Within 7 days after the effective date of this AD, unless already accomplished within the last 7 days, visually inspect P/N 7958533-517 (Hartwell P/N H2816-3) cowl door latch assemblies for fractures, paying particular attention to the attachment hook. Perform this inspection in accordance with McDonnell Douglas Alert Service Bulletin A71-42, dated June 24, 1987 (hereinafter referred to as ASB A71-42), or later FAA-approved revisions.

1. If fracture is found, prior to further flight replace all latch assemblies on the affected door.

2. If fracture is not found, repeat the visual inspections of the cowl door latches at intervals not to exceed 7 days, until such time as P/N 7958533-517 (Hartwell P/N H2816-3) latch assemblies are replaced with new P/N 7958533-519 (Hartwell P/N H2816-5) latch assemblies in accordance with ASB A71-42.

D. Installation of new cowl door latches, P/N 7958533-519 (Hartwell P/N 2816-5), constitutes terminating action for this AD.
