United States Rail Service Issues
The Surface Transportation Board (Board) will hold a public hearing on April 10, 2014, at its offices in Washington, DC, to provide interested persons the opportunity to report on recent service problems in the United States rail network, to hear from rail industry executives on plans to address their service problems, and to discuss additional options to improve service.
Airworthiness Directives; Hawker Beechcraft Corporation Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (Type Certificate previously held by Mitsubishi; Raytheon Aircraft Company) Model MU-300 airplanes, and Hawker Beechcraft Corporation (Type Certificate previously held by Raytheon Aircraft Company; Beech Aircraft Corporation) Model 400, 400A, and 400T airplanes. This proposed AD was prompted by multiple reports of fatigue cracking in the horizontal stabilizer ribs. This proposed AD would require repetitive inspections of the horizontal stabilizer rib assemblies for cracking, and replacement if necessary. We are proposing this AD to detect and correct such cracking, which could result in the failure of the horizontal stabilizer and loss of pitch control of the airplane.
Airworthiness Directives; Dassault Aviation Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by a report of a crew alerting system message caused by an inversion of the wiring in the slats control manifold (SCM). This proposed AD would require doing an operational test of the SCM, and replacing the affected SCM with a serviceable SCM if necessary. We are proposing this AD to detect and correct inversion of the wiring in the SCM, which could lead to a commanded retraction of the median and outboard slats in flight, and result in reduced controllability of the airplane.
