Plain English Summary

3/10 complexity

CASA requires immediate structural reinforcement of the vertical and horizontal stabiliser spars on Twin Commander (Gulfstream/Rockwell/Aero Commander) Models 500, 560, 560A, 560E, 680, 680E and 720, serial numbers 151–710. Owners/operators must arrange and pay for the work and comply "forthwith."
