The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model DC-8-11, DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8- 33, DC-8-41, DC-8-42, and DC-8-43 airplanes; Model DC-8-50 series airplanes; Model DC-8F-54 and DC-8F-55 airplanes; Model DC-8-60 series airplanes; Model DC-8-60F series airplanes; Model DC-8-70 series airplanes; and Model DC-8-70F series airplanes. This AD requires repetitive high frequency eddy current or repetitive low frequency eddy current inspections for cracks on the area around certain fasteners of the access opening doubler on the left and right wing center spar lower cap, and repair, if necessary. This AD was prompted by reports that cracks in the center spar lower cap and, in some cases, the web of the spar, have been found at stations Xrs = 168.00, Xrs = 251.00, and Xrs = 358.00. We are issuing this AD to detect and correct cracks in the area around certain fasteners of the access opening doubler on the left and right wing center spar lower cap, which could compromise the structural integrity of the wing structure.

Piper Aircraft, Inc. Airplanes
We are revising an existing airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-23, PA-23-160, PA-23-235, PA-23- 250, PA-23-250 (Navy UO-1), PA-E23-250, PA-31, PA-31-300, PA-31-325, PA-31-350, PA-31P, PA-31P-350, PA-31T, PA-31T1, PA-31T2, PA-31T3, PA- 42, PA-42-720, and PA-42-1000 airplanes that are equipped with a baggage door in the fuselage nose section (a nose baggage door). That AD currently establishes life limits and replacement requirements for safety-critical nose baggage door components and repetitive inspections and lubrication of the nose baggage door latching mechanism and lock assembly. This new AD removes the requirement for the nose baggage door compartment interior light inspection and retains the other requirements from AD 2009-13-06, Amendment 39-15944. This AD was prompted by further investigation and a request for an alternative method of compliance (AMOC). We are issuing this AD to correct the unsafe condition on these products.

The Boeing Company Model 737-600, -700, -700C, -800, and -900 Series Airplanes
We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires replacement of the power control relays in the P91 and P92 power distribution panels for the fuel boost and override pumps with new, improved relays having a ground fault interrupter (GFI) feature, or installation and maintenance of universal fault interrupters (UFIs) using a certain supplemental type certificate. This new AD continues to require the actions of the existing AD and also specifies which relays may be replaced by GFIs or UFIs. This AD was prompted by a need to clarify which relays may be replaced by installation of UFIs. We are issuing this AD to prevent pump housing burn-through due to electrical arcing, which could create a potential ignition source inside a fuel tank. This condition, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

Austro Engine GmbH Model E4 Diesel Piston Engines
We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires frequent inspections of the fuel pressure supply for excessive oscillations to determine if high-pressure (HP) fuel pumps have been exposed to damaging pressure oscillations. Pumps that have been exposed require replacement before further flight. This new AD requires the initial and repetitive inspections of AD 2010-23-09, but also requires installing HP fuel pump part number (P/N) E4A-30-200-000, as mandatory terminating action to the repetitive inspections. We are issuing this AD to prevent engine power loss or in-flight shutdown, which could result in loss of control of the airplane.
