Plain English Summary

1/10 complexity

What this does: This document officially cancels a 49-year-old safety rule that required owners of Brantly B-2 helicopters to modify their rotor blade hinges.

Who it affects: Owners and operators of Brantly B-2 Series Helicopters (though in practice, no one is affected anymore).

Why it matters: Back in 1960, the Civil Aviation Safety Authority (CASA) issued an urgent directive requiring helicopter owners to modify their rotor blade hinges. This was to prevent stress damage during emergency landings when the rotor was spinning slowly. Because the required fix was immediate ("forthwith") and all affected helicopters have long since been modified, the rule is now obsolete. This cancellation simply removes the dead rule from the aviation safety books.

AD/B-2/10	Rotor Blade Hinge - Modification	6/2009

Requirement:	CANCELLED.
	This AD is cancelled on 4 June 2009.
Background:	This AD, issued in 1960, required modification of the rotor blade hinge in accordance with Brantly SL No. 11 to reduce the compressive stresses during low rotor RPM power-off landings. The AD compliance was forthwith. As all aircraft would have been modified, the AD is no longer required.
