SUPPLEMENTARY INFORMATION:
Background
The FAA is adopting a new airworthiness directive AD for Bell Textron Canada Limited type certificate previously held by Bell Helicopter Textron Canada Limited Bell Model 505 helicopters. This AD was prompted by the discovery of a gap between the transmission restraint assembly aft attachment hardware lower washer and mating airframe truss assembly truss assembly clevis lower lug. This AD
requires inspecting the transmission restraint aft attachment hardware installation for a gap and corrective action depending on the inspection results. The FAA is issuing this AD to address the unsafe condition on these products.

SUMMARY:

Examining the AD Docket
VerDate Sep<11>2014

31089

The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to Bell Model 505 helicopters with a truss assembly part number P/N SLS030056015 with a serial number S/N listed in Attachment A of Bell Alert Service Bulletin ASB 505
1912, Revision A, dated July 11, 2019
5051912 Rev A. The NPRM
published in the Federal Register on March 22, 2021 86 FR 15146. In the NPRM, the FAA proposed to require the following within 100 hours time-inservice TIS:
Accessing and cleaning the lower attachment hardware securing the restraint to the truss assembly, loosening the torque on each lower nut to measure the tare, and adding a torque value of 20 inch-lbs to the measured tare of each nut and torqueing each nut to this new total value.
Inspecting for a gap around the circumference between the nut and the washer and between the washer and the truss assembly clevis lower lug mounting surface of the right-hand RH
and left-hand LH sides, and if there is a gap, measuring the gap.
If there is a gap that is less than 0.003 inch 0.076 mm, installing the hardware using the original torque value of 40 to 58 foot-pounds 55 to 78 Nm plus tare and completing the installation of the attachment point.
If there is a gap that is 0.003 inch 0.076 mm to 0.020 inch 0.508 mm inclusive, installing the hardware with a decreased torque value limit of 20 to 60 inch-pounds 2.3 to 6.8 Nm plus tare and completing the installation of the attachment point. The NPRM also proposed to require updating records for your helicopter to indicate the new torque limits on one or both sides.
Thereafter, within 100 hours TIS, and thereafter at intervals not to exceed 100
hours TIS, the NPRM proposed to
