Special Airworthiness Information Bulletins (4)

Advisory bulletins on these airframes. Not mandatory like ADs — but operators tracking AD compliance often miss the SAIB on the same component.

Special Conditions + ELOS findings

Certification-time deviations: SCs add requirements where the design is novel; ELOS allows alternative compliance. Most modern types have both.

Certification basis — 14 CFR
