EASA AD CF-2023-73
SUPERSEDED BY TCCA AD CF-2025-71
Summary
Canadian Airworthiness Directive CF-2023-73 is issued for Pratt & Whitney Canada PW814GA and PW815GA engines. It introduces updated airworthiness limitations including revised life limits and mandatory inspection intervals for certain engine components. This directive ensures continued airworthiness by mandating compliance with the latest maintenance standards.
What Changed
CF-2023-73 updates the airworthiness limitations manual (ALM) for PW814GA and PW815GA engines based on re-analysis of certification and in-service data. It revises cyclic life limits and mandatory inspection intervals for life-limited parts and critical components. The directive requires operators to follow the updated ALM Issue No. 020 dated 11 July 2023 or later approved revisions.
Why It Matters
This directive is critical for aviation professionals to prevent unsafe conditions caused by exceeding updated life limits on engine components. Operators and maintenance organizations must adjust their maintenance programs to comply with the new inspection and replacement schedules. Failure to comply could lead to engine damage or failure, impacting flight safety and regulatory compliance.
What To Do
Operators of PW814GA and PW815GA engines must ensure no engine parts are installed or remain installed unless they comply with the updated limitations and maintenance tasks in ALM Issue No. 020 dated 11 July 2023. They must perform mandatory inspections and replacements as specified and may use later approved ALM revisions. Compliance is required as of the effective date, 2023-11-17.
