Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD, do a detailed visual inspection for protruding, loose, or missing fasteners of the upper and lower engine pylons, in accordance with Bombardier Temporary Revision (TR) 54-0007, dated March 8, 2016, to the CRJ700/900/1000 Aircraft Maintenance Manual. Repeat the inspection thereafter at intervals not to exceed 1,500 flight hours. (1) For airplanes that have accumulated more than 840 total flight hours as of the effective date of this AD: Inspect within 660 flight hours or 3 months, whichever occurs first, after the effective date of this AD. (2) For airplanes that have accumulated 840 total flight hours or less as of the effective date of this AD: Inspect before the accumulation of 1,500 total flight hours.

Unsafe condition

This AD was prompted by reports of loose or missing Hi-Lite fasteners on the upper and lower engine pylon structure common to the upper and lower pylon skin panels and engine thrust fitting. We are issuing this AD to detect and correct protruding, loose, or missing fasteners, which could result in structural failure of the engine pylons.

Affected ADs
