Ninth Meeting-RTCA Special Committee 217: Joint With EUROCAE WG-44 Terrain and Airport Mapping Databases
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 217: Joint with EUROCAE WG-44 Terrain and Airport Mapping Databases.
Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Model PIAGGIO P-180 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; The Boeing Company Model 747 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require repetitive general visual inspections for broken or missing latch pins of the lower sills of the forward and aft lower lobe cargo doors; repetitive detailed inspections for cracking of the latch pins; and corrective actions if necessary. This proposed AD was prompted by reports of fractured latch pins found in service; investigation revealed that the cracking and subsequent fracture were initiated by fatigue and propagated by a combination of fatigue and stress corrosion. We are proposing this AD to detect and correct fractured or broken latch pins, which could result in a forward or aft lower lobe cargo door opening and detaching during flight, and consequent rapid decompression of the airplane.
Airworthiness Directives; The Boeing Company Model 737-200, -200C, -300, -400, and -500 Series Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain Model 737-300, -400, and -500 series airplanes. The existing AD currently requires repetitive external non-destructive inspections to detect cracks in the fuselage skin along the chem-mill step at stringers S-1 and S-2 right, between station (STA) 827 and STA 847, and repair if necessary. Since we issued that AD, we have received reports of additional crack findings of the fuselage crown skin at the chem-milled steps. This proposed AD would add inspections for cracking in additional fuselage crown skin locations, and repair if necessary. This proposed AD would also reduce the inspection thresholds for certain airplanes, extend certain repetitive inspection intervals, and add airplanes to the applicability of the existing AD. We are proposing this AD to detect and correct fatigue cracking of the fuselage skin panels at the chem- milled steps, which could result in sudden fracture and failure of the fuselage skin panels, and consequent rapid decompression of the airplane.
Standard Operating Procedures (SOP) of the Aircraft Certification Service (AIR) Process for the Sequencing of Certification and Validation Projects
This notice announces the availability of and request for public comments on the Aircraft Certification Service (AIR) standard operating procedure (SOP) describing the process used to sequence certification projects that are anticipated to take more than 40 hours of FAA involvement to complete.
Airworthiness Directives; Lycoming Engines (Type Certificate Previously Held by Textron Lycoming) Reciprocating Engines
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require removing certain ``machined-from-billet'' Volare LLC (formerly Precision Airmotive Corporation, formerly Facet Aerospace Products Company, formerly Marvel-Schebler (BorgWarner)) HA-6 carburetors, inspecting for a loose mixture control sleeve or for a sleeve that may become loose, repairing the carburetor, or replacing the carburetor with one eligible for installation. This proposed AD was prompted by a report of a ``machined-from-billet'' HA-6 carburetor having a loose mixture control sleeve that rotated in the carburetor body causing restriction of fuel and power loss. We are proposing this AD to prevent engine in-flight shutdown, power loss, and reduced control of the airplane.
Airworthiness Directives; 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.
