If clamps are incorrectly installed or missing, before further flight, install clamps by following the Accomplishment Instructions, paragraph 3.A.(4) through 3.A.(17) of the ASB. (3) After each maintenance that requires removing clamps, comply with paragraphs (f)(1) and (f)(2) of this AD.

Unsafe condition
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Affected ADs
This AD defines the unsafe condition as an incorrectly installed clamp that does not provide adequate clearance to prevent chafing between the high voltage electrical lines and the hydraulic hoses. This condition could result in a fire in an area of the helicopter without extinguishing capability and subsequent loss of control of the helicopter.
