Boeing Wants FAA To Exempt MAX 7 From Safety Rules To Get It in the Air
Little noticed, days before the holiday break, Boeing petitioned the Federal Aviation Administration for an exemption from key safety standards for the 737 MAX 7 -- the still-uncertified smallest member of its newest jet family. Seattle Times: Since August, earlier models of the MAX currently flying passengers in the U.S. have had to limit use of the jet's engine anti-ice system after Boeing discovered a defect in the system with potentially catastrophic consequences. The flaw could cause the inlet at the front end of the pod surrounding the engine -- known as a nacelle -- to break and fall off. In an August Airworthiness Directive, the FAA stated that debris from such a breakup could penetrate the fuselage, putting passengers seated at windows behind the wings in danger, and could damage the wing or tail of the plane, "which could result in loss of control of the airplane." Dennis Tajer, a spokesperson for the Allied Pilots Association, the union representing 15,000 American Airlines pilots, said the flaw in the engine anti-ice system has "given us great concern." He said the pilot procedure the FAA approved as an interim solution -- urging pilots to make sure to turn off the system when icing conditions dissipate to avoid overheating that within five minutes could seriously damage the structure of the nacelle -- is inadequate given the serious potential danger. "You get our attention when you say people might get killed," Tajer said. "We're not interested in seeing exemptions and accommodations that depend on human memory. ... There's just got to be a better way." In its petition to the FAA, Boeing argues the breakup of the engine nacelle is "extremely improbable" and that an exemption will not reduce safety. "The 737 MAX has been in service since 2017 and has accumulated over 6.5 million flight hours. In that time, there have been no reported cases of parts departing aircraft due to overheating of the engine nacelle inlet structure," the filing states.
