Airworthiness Directives; Pacific Aerospace Limited Airplanes
Document Number: 2018-05355
Type: Rule
Date: 2018-03-19
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the possibility for the control column to snag on the cockpit control tee handles on certain airplanes. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Costruzioni Aeronautiche Tecnam srl Airplanes
Document Number: 2018-05138
Type: Proposed Rule
Date: 2018-03-19
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as an incorrect part number for the rudder trim actuator is referenced in the Airworthiness Limitations section of the FAA-approved maintenance program (e.g., maintenance manual) and the life limit for that part may not be properly applied in service. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-05016
Type: Rule
Date: 2018-03-19
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-300 and -500 series airplanes. This AD was prompted by a report indicating that fatigue cracks were found in the lower wing skin of an airplane with winglets installed. This AD requires repetitive inspections for cracking of the lower wing skin, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
