## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Pilatus Britten-Norman BN2, BN2A, and BN2B series airplanes that have been modified with a 70 amp direct current (DC) Generation System. The proposed action would require removing the 70 amp terminal diodes and installing new terminal diodes with a higher amp rating. Reports from operators that one or both diodes were failing prompted the proposed action. The actions specified by the proposed AD are intended to prevent loss of electrical power to the navigation, communications and light systems, which could impair the pilots ability to maintain control of the airplane.
