Federal Aviation Administration March 26, 2008 – Federal Register Recent Federal Regulation Documents

The FAA proposes to amend the certification standards for aircraft engines to introduce requirements for approval of maximum engine overtorque. This action would add a new engine overtorque test, amend engine ratings and operating limitations, and define maximum engine overtorque for certain turbopropeller and turboshaft engines. The proposed rule is intended to harmonize applicable U.S. and European standards and simplify airworthiness approvals for import and export of aircraft engines.

We propose to adopt a new airworthiness directive (AD) for all Boeing Model 737-300, -400, and -500 series airplanes. This proposed AD would require repetitive inspections for discrepancies of the fuse pins of the inboard and outboard midspar fittings of the nacelle strut, and corrective actions if necessary. This proposed AD results from a report of corrosion damage of the chrome runout on the head side found on all four midspar fuse pins of the nacelle strut. Additionally, a large portion of the chrome plate was missing from the corroded area of the shank. We are proposing this AD to detect and correct discrepancies of the fuse pins of the inboard and outboard midspar fittings of the nacelle strut, which could result in reduced structural integrity of the fuse pins and consequent loss of the strut and separation of the engine from the airplane.

We are adopting a new airworthiness directive (AD) for the products listed above. This 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:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 \1/8\-inch rivets installed in place of the correct \5/32\-inch rivets that secure the horizontal tail surface load transfer angles to the rearmost fuselage frame at Station 384.62. We are issuing this AD to require actions to correct the unsafe condition on these products.

The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on December 6, 2007, vol. 72, no. 234, page 68949. This collection maintains a reservation reporting system for unscheduled instrument flight rule (IFR) arrivals at Chicago's O'Hare International Airport.

The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on December 6, 2007, vol. 72, no. 234, page 68950. The respondents supply information to the FAA Civil Aviation Registry's Aircraft Registration Branch in order to obtain an authorization code for access to the International Registry.

The FAA is adopting a new airworthiness directive (AD) for certain Avidyne Corporation (Avidyne) Primary Flight Displays (PFDs) (Part Numbers (P/Ns) 700-00006-000, -001, -002, -003, and -100) that are installed on airplanes. This AD requires a check of the maintenance records and inspection of the PFD (if necessary) to determine if an affected serial number PFD is installed. If an affected serial number PFD is installed, this AD requires you to incorporate information that limits operation when certain conditions for the PFD or backup instruments exist. This AD results from several field reports of PFDs displaying incorrect altitude and airspeed information. We are issuing this AD to prevent certain conditions from existing when PFDs display incorrect attitude, altitude, and airspeed information. This could result in airspeed/altitude mismanagement or spatial disorientation of the pilot with consequent loss of airplane control, inadequate traffic separation, or controlled flight into terrain.
