Plain English Summary

3/10 complexity

This AD, issued by the Civil Aviation Safety Authority, makes compliance with Nomad Service Bulletin NMD‑55‑7 mandatory: owners/operators and maintenance organisations of GAF Nomad N22, N22B and N24 aircraft must carry out weather‑proofing work on the horizontal stabiliser to address water ingress. The directive shifts the SB’s previously voluntary tasks into compulsory action, with affected operators bearing the cost and relying on the service bulletin for technical detail and deadlines.
