Plain English Summary

1/10 complexity

What this does: This instrument cancels three specific Airworthiness Directives (ADs) — mandatory safety notices that previously required aircraft owners to perform particular maintenance tasks or modifications.

Who it affects: Owners and operators of:

AgustaWestland AW139 helicopters (AD/AB139/7 Amdt 1)
Cessna 650 Citation aircraft (AD/CESSNA 650/2)
Lancair LC40 aircraft (AD/LC40/3 Amdt 1)

What changes: As of the specified dates (11 February 2011 for the first two, 14 March 2011 for the third), these three ADs no longer apply. This removes the legal obligation for operators to comply with the specific maintenance requirements previously mandated by those directives.

Why it matters: Revoking an AD typically happens when a safety issue has been resolved through design changes, the requirement is found to be unnecessary, or it has been replaced by a newer directive. This reduces compliance costs and regulatory burden for operators of these specific aircraft models.
