Applicability*9
This AD applies to all Leonardo S.p.A. Model AB139 and AW139 helicopters, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions

Unsafe condition
This AD was prompted by a report of interference found in the overhead panel area between the electrical cables and adjacent connectors. The FAA is issuing this AD to detect and address chafing of the electrical cables. The unsafe condition, if not addressed, could result in chafing of the electrical cables which could lead to a fire in the overhead panel with consequent loss of control of the helicopter.
Affected ADs
None.
