Belly fairing protection

Effectivity: All Learjet 40/45/70/75 aircraft

ATA 57

Removable belly fairing panels are attached on three sides using hardware and on the remaining side using spring clips. These clips allow the wing to panel interface to flex. This flexing has caused degradation to the finish on some attaching surfaces. To alleviate the finish wear, Bombardier has a solution to mitigate this wear.

Bombardier would like to inform customers of the release of SB40-57-07, SB45-57-14, SB70-57-03, and SB75-57-02 for all Learjet 45 aircraft. These service bulletins allow installation of rub strips and erosion tape to alleviate chaffing/finish wear and minimize the potential for corrosion on the mounting flanges.
