Airworthiness Directives; Hawker Beechcraft Corporation Model G58 Airplanes
Document Number: E9-29984
Type: Proposed Rule
Date: 2009-12-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model G58 airplanes. This proposed AD would require inspecting the installation of stand-off hardware between the heater fuel line and the heater over-temperature sensor wires for minimum clearance and installing acceptable stand-off hardware if stand-off hardware is missing or inadequate. This proposed AD would also require inspecting the brake reservoir line and the fuel heater power wire for damage and minimum clearance, replacing any damaged wires and/or lines, and installing stand-off hardware if minimum clearance is not met. This proposed AD results from reports received of a power wire shorting out on the brake reservoir tube. We are proposing this AD to detect and correct inadequate clearance of the brake reservoir tubing and the heater fuel pump wiring, which could result in chafing and shorting out of the electrical wiring and chafing of the tubing carrying flammable fluids. This condition could lead to a fire in the nose wheel well.
Airworthiness Directives; Cessna Aircraft Company (Type Certificate Previously Held by Columbia Aircraft Manufacturing (Previously The Lancair Company)) Models LC40-550FG, LC41-550FG, and LC42-550FG Airplanes
Document Number: E9-29982
Type: Proposed Rule
Date: 2009-12-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2009-09- 09, which applies to certain Cessna Aircraft Company (Cessna) (type certificate previously held by Columbia Aircraft Manufacturing (previously The Lancair Company)) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. AD 2009-09-09 currently requires repetitive inspections of the rudder hinges and the rudder hinge brackets for damage, i.e., cracking, deformation, and discoloration. If damage is found during any inspection, AD 2009-09-09 also requires replacing the damaged rudder hinge and/or rudder hinge bracket. Since we issued AD 2009-09-09, Cessna has developed a modification that, when incorporated, would terminate the repetitive inspections required by AD 2009-09-09. The FAA has determined that long-term continued operational safety will be better assured by design changes that removed the source of the problem, rather than by repetitive inspections or other special procedures. Consequently, this proposed AD would retain the inspection requirements of AD 2009-09-09 and add a terminating action for the inspection requirements. We are proposing this AD to detect and correct damage in the rudder hinges and the rudder hinge brackets, which could result in failure of the rudder. This failure could lead to loss of control.
Airworthiness Directives; Hawker Beechcraft Corporation (Type Certificate Previously Held by Raytheon Aircraft Company) Models B300 and B300C Airplanes
Document Number: E9-29975
Type: Proposed Rule
Date: 2009-12-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (type certificate previously held by Raytheon Aircraft Company) Models B300 and B300C airplanes. This proposed AD would require you to inspect the terminal board on the circuit card rack assembly to determine if the correct bus bar is installed. This proposed AD would also require you to replace the bus bar if necessary and inspect the left and right pitot heat annunciators for proper operation. This proposed AD results from reports of the left and right pitot heat annunciators not illuminating for an inoperative pitot heat condition. We are proposing this AD to detect and correct installation of an incorrect bus bar, which could result in failure of the pitot heat annunciators to illuminate. This failure could lead to the pilot being unaware that moisture has frozen on the pitot tube(s) and cause erroneous flight instrument indication.
