Aviation Rulemaking Advisory Committee (ARAC) Airman Testing Standards and Training Working Group (ATSTWG)
This notice announces the availability of additional draft Airman Certification Standards (ACS) documents developed by the ATSTWG for the authorized instructor certificate, the private pilot certificate and the instrument rating. These documents are available for public review, download, and comment.
Airworthiness Directives; Dassault Aviation Airplanes
We propose to adopt a new airworthiness directive (AD) for all DASSAULT AVIATION Model FAN JET FALCON; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by reports of defective fire extinguisher bottle cartridges. This proposed AD would require checking manufacturing references of pyrotechnical cartridges for batch number and date, repetitive checking of cartridges for electrical continuity, and replacing defective pyrotechnical cartridges if necessary. We are proposing this AD to detect and correct defective fire bottle cartridges, which could affect the capability to extinguish a fire in an engine, auxiliary power unit, or rear compartment, which could result in damage to the airplane and injury to the occupants.
Airworthiness Directives; BAE Systems (Operations) Limited Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. The existing AD currently requires revising the maintenance program by incorporating certain airworthiness limitations that require new life limits on certain main landing gear (MLG) components. Since we issued that AD, we have determined that reduced safe life limits on certain nose landing gear (NLG) fittings are necessary. Analysis of these fittings showed the presence of forging indications in the flash line, which might reduce the life limits of these fittings.
Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters
We are adopting a new airworthiness directive (AD) for Eurocopter Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, and AS350D1 helicopters with a single hydraulic system and a certain hydraulic pump drive installed. This AD requires inspecting the hydraulic pump drive pulley bearing (pulley bearing) for leaks, rust, overheating, and condition. This AD is prompted by six reports of hydraulic pump drive belt failure caused by seizure of the pulley bearing. These actions are intended to prevent hydraulic pump drive belt failure, loss of hydraulic servo assistance, and subsequent loss of control of the helicopter.
