Commonwealth legislation
Sets mandatory retirement hour limits for the Transavia PL-12 family’s main and stub wings, with different hour caps by model, serial number and mod configuration. Operators must retire or otherwise address those wing structures when the listed hours are reached; compliance is required forthwith and the amendment became effective 5 August 2004.
The manufacturer’s fatigue evaluations are cited as the basis. Aircraft owners/operators will bear costs of earlier retirement or replacement, and the Civil Aviation Safety Authority (delegate) enforces the requirement.
