What to do
Operators must perform initial eddy current or fluorescent penetrant inspections within specified cycle limits depending on engine configuration, followed by repetitive inspections at defined intervals. If cracks of 0.25 inches or more are found, the affected turbine rear frame must be replaced before further flight. Compliance with inspection schedules and corrective actions is mandatory from the effective date of 19 March 2021.
Summary
EASA Airworthiness Directive 2021-0062 is an airworthiness directive addressing inspection and replacement requirements for low pressure turbine rear frames on CFM International CFM56-5B series engines, commonly installed on Airbus A318, A319, A320, and A321 aircraft. The directive mandates inspections for cracks in specific turbine rear frame parts and outlines corrective actions to prevent engine failure.
What changed
This directive supersedes EASA AD 2016-0039 and corrects an error in the compliance times for inspections, particularly reducing intervals for post-SB 72-0308 (corporate) engines. It retains previous inspection and replacement requirements but introduces updated inspection intervals and compliance times based on engine configuration.
Why it matters
This directive is critical for aviation professionals to prevent potential failure of turbine rear frames that could lead to engine separation and reduced aircraft control. Operators and maintenance organizations must ensure timely inspections and replacements to maintain airworthiness and comply with regulatory requirements, thereby safeguarding flight safety and avoiding costly unscheduled maintenance.
