Plain English Summary

3/10 complexity

This airworthiness directive covers Piaggio P.166 aeroplanes fitted with nose‑wheel girder P/N 4105‑033 that have more than 1,600 hours. It requires owners/operators to inspect the weld area of the steering girder (para.1) and, within a set deadline, either replace it with reinforced girder P/N 4105‑016B or have it modified under an approved scheme (para.2).

The rule shifts recurring inspection and parts/rework costs to aircraft owners/operators, mandates 100‑hour inspection intervals until modification, and requires approval for alternative modification schemes, creating maintenance planning and compliance obligations.
