What to do
Affected operators must inspect the front and rear canopy locking rods before the next flight after the effective date and during each daily inspection, and perform annual checks as specified. Any discrepancies found require repair before further flight. Additionally, the Aircraft Flight Manual must be amended within three months of the effective date, and all pilots informed of the changes.
Summary
EASA Airworthiness Directive 2019-0237R1 is an amendment addressing inspection, check, and repair requirements for the canopy lock and rear locking rods on DG-Flugzeugbau GmbH DG-500 and DG-1000 sailplanes and powered sailplanes. This directive applies to all serial numbers of DG-500 variants and DG-1000S and DG-1000T sailplanes up to serial number 10-144 inclusive. It mandates inspections and repairs to ensure the canopy locking mechanisms function correctly to prevent blockage of the emergency canopy release system.
What changed
EASA Airworthiness Directive 2019-0237R1 revises the original AD 2019-0237-E by removing references to specific Technical Note instruction paragraphs that have changed with the updated TN issue 01.b. The revised Technical Notes were added to the list of reference publications, updating inspection and repair instructions accordingly.
Why it matters
This directive is critical for aviation professionals because failure of the canopy locking rods can block the emergency canopy release system, potentially preventing safe occupant escape during an in-flight emergency. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The AD also requires amendments to the Aircraft Flight Manual, affecting pilot operating procedures.
