Airworthiness Directives; Honeywell International Inc. Turboshaft Engines
Transportation Department, Federal Aviation Administration
What is this?
This is a regulatory record from Transportation Department, Federal Aviation Administration — a rule, proposed rule, or notice. Regulations carry the force of law once final, and often invite public comment before that point.
Why does it matter?
Regulations are usually what actually binds you, more than statutes are. This is where an agency states the requirement, the effective date, and whether there is still a window to respond.

Description
We are adopting a new airworthiness directive (AD) for Honeywell International Inc. LTS101-600A-2, -3, -3A, and LTS101-700D-2 turboshaft engines with certain power turbine governors (PTG) model AL- AB1, installed, that are marked with compliance symbol N or P, or with no compliance symbol, on the PTG identification plate. This AD requires initial and repetitive replacements of the affected PTGs. This AD was prompted by reports of two accidents where the engines suddenly lost power and the helicopters had to make emergency autorotation landings, leading to substantial damage to the helicopters. We are issuing this AD to prevent loss of engine power, leading to emergency autorotation landing and damage to the helicopter.
