Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 30 days after the effective date of this AD, request instructions from the Manager, International Section, Transport Standards Branch, FAA, to address the unsafe condition specified in paragraph (e) of this AD; and accomplish the actions at the times specified in, and in accordance with, those instructions. Guidance can be found in Mandatory Continuing Airworthiness Information (MCAI) European Aviation Safety Agency (EASA) AD 2012-0239, dated November 9, 2012.

Unsafe condition

This AD was prompted by reports indicating that certain exit signs have a hydrogen isotope that decays over time, causing the signs to lose their brightness. We are issuing this AD to prevent insufficiently illuminated exit signs, which could possibly prevent safe evacuation during an emergency and cause injury to occupants.

Affected ADs

None.
