Airworthiness Directive 2013-11-05

What this AD requires
We are adopting a new airworthiness directive (AD) for Bell Model 214B, 214B-1, and 214ST helicopters with a certain tail rotor hanger bearing (bearing) installed. This AD requires inspecting the bearing to determine whether an incorrectly manufactured seal material is installed on the bearing. This AD is prompted by a report that certain bearings were manufactured with an incorrect seal material that does not meet Bell specifications. The actions specified by this AD are intended to prevent loss of bearing grease, failure of the bearing, and subsequent loss of control of the helicopter.
Which aircraft AD 2013-11-05 applies to
Model 214B and 214B-1, S/N 28001 through 28070; Model 214ST, S/N 28101 through 28200; applies only with tail rotor hanger bearing P/N 214-040-606-005 or 214-040-606-101 installed. Condition is a bearing with incorrect seal material.
Whether AD 2013-11-05 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
