Leonardo Pilots: Recheck Those Botched Torque Nuts for Cracks Now

## Summary

If you fly a Leonardo helicopter like the A109 or AW119, listen up! The FAA found some maintenance instructions had wrong torque numbers for important parts, so they’re making sure those parts get checked regularly for cracks or damage. This keeps your helicopter safe and sound without breaking the bank or your schedule.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model A109E, A109S, AW109SP, A119, and AW119 MKII helicopters. This AD was prompted by a report that certain manufacturer maintenance instructions for swashplate assembly installation specified incorrect torque values for certain swashplate nuts. This AD requires repetitively inspecting certain swashplate nuts for cracks, fretting, or slippage marks and, depending on the results, performing corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- Mandatory swashplate nut inspections: cost, medium. If you operate a Leonardo helicopter Model A109E, A109S, AW109SP, A119, or AW119 MKII, the FAA now requires repetitive inspections of certain swashplate nuts for cracks, fretting, or slippage marks. You must perform these inspections at the recurring intervals the AD requires to address the unsafe…
- Required corrective actions if defects found: cost, medium. If an inspection finds cracks, fretting, or slippage marks on the specified swashplate nuts, the AD requires performing corrective actions specified by the FAA, which may include repair or replacement of parts. Operators must complete those corrective actions to address the unsafe condition on the…
