This action corrects a typographical error that appeared in a final rule, which the FAA published in the Federal Register. In that final rule, the FAA inadvertently changed a word. The intent of this action is to correct the error in the regulation to ensure the requirement is clear and accurate.

Airworthiness Directives; BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes

Fri, Jun 20 2008 11:00:00 GMT

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. The existing AD currently requires repetitive tests for free movement of the capsule/bearing of the nose landing gear (NLG), and related investigative and corrective actions. This proposed AD would require a modified test for free movement of the capsule/bearing of the NLG at reduced repeat intervals, and replacement of the NLG assembly with a modified assembly. This proposed AD results from additional reports of the NLG failing to extend fully on an airplane that had been inspected in accordance with AD 20041407. We are proposing this AD to prevent failure of the NLG to extend fully, which could result in reduced controllability of the airplane during landing.

Airworthiness Directives; Boeing Model 707 Airplanes and Model 720 and 720B Series Airplanes

Fri, Jun 20 2008 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for all Boeing Model 707 airplanes and Model 720 and 720B series airplanes. This proposed AD would require performing an operational test of the engine fuel suction feed of the fuel system, and other related testing if necessary. This proposed AD results from a report of inservice occurrences of loss of fuel system suction feed capability, followed by total loss of pressure of the fuel feed system. We are proposing this AD to detect and correct failure of the engine fuel suction feed of the fuel system, which could result in multiengine flameout, inability to restart the engines, and consequent forced landing of the airplane.

Airworthiness Directives; Boeing Model 727 Airplanes

Fri, Jun 20 2008 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 727 airplanes. This proposed AD would require performing an operational test of the engine fuel suction feed of the fuel system, and other related testing if necessary. This proposed AD results from a report of inservice occurrences of loss of fuel system suction feed capability, followed by total loss of pressure of the fuel feed system. We are proposing this AD to detect and correct failure of the engine fuel suction feed of the fuel system, which could result in multiengine flameout, inability to restart the engines, and consequent forced landing of the airplane.

Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 440) Airplanes

Fri, Jun 20 2008 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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:

Bombardier Aerospace has completed a system safety review of the aircraft fuel system against fuel tank safety standards * * *. [A]ssessment showed that supplemental maintenance tasks [for certain bonding jumpers, wiring harnesses, and hydraulic systems, among other items] are required to prevent potential ignition sources inside the fuel system, which could result in a fuel tank explosion. * * *
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes, and Model

Fri, Jun 20 2008 11:00:00 GMT

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model EMB135 airplanes and Model EMB145, 145ER, 145MR, 145LR, 145XR, 145MP, and 145EP airplanes. The existing AD currently requires replacing the metallic tubes enclosing the vent and pilot valve wires in the left and right hand wing fuel tanks with nonconductive hoses. This proposed AD would add airplanes to the applicability of the existing AD. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent an ignition source inside the fuel tank that could ignite fuel vapor and cause a fuel tank explosion and loss of the airplane.
