Federal safety officials are making another push for stricter oversight of air tour operators and hot-air balloon rides after several deadly crashes in recent years. The National Transportation Safety Board on Tuesday asked the Federal Aviation Administration to raise safety requirements for the passenger-carrying operations, which fall under less restrictive regulations than airlines do for things such as pilot training and maintenance. \u201cWhen people step onboard an aircraft as paying passengers, they have the right to trust that the flight will be operated as safely as possible,\u201d NTSB Chairman Robert Sumwalt said at the end of a board hearing on the matter. Some airplane and helicopter tours operate under rules for \u201cgeneral aviation,\u201d a category that mostly covers private planes not used to carry paying passengers. Safety board members said some of the operators exploit loopholes in FAA regulations to avoid stricter oversight. The FAA said in a statement that it \u201chas a number of initiatives underway to improve the safety\u201d of passenger-carrying general aviation operations, including requiring air tour operators to have safety-management programs and requiring balloon pilots to pass medical exams. Under current FAA rules, air tours are subject to more inspections than other private planes, tours must take off and land at the same airport, and operators must have drug and alcohol testing programs for employees. NTSB members said, however, those steps aren\u2019t enough and that some tour operators evade closer monitoring by how they describe their flights. Board members cited a 2018 helicopter tour over New York City that was using an exception granted for aerial photography when it crashed, killing all five passengers, and the 2017 crash in California of an acrobatic stunt plane that killed the pilot and passenger \u2014 it was operating as an instructional flight. \u201cThis is one of the most egregious examples of exploiting a loophole, in my opinion,\u201d board member Jennifer Homendy said of the California crash. She said the operator, Sky Combat Ace, advertised an \u201cadrenaline rush package\u201d and other thrill-seeking rides. \u201cDoes that sound like a flight school?\u201d The company disputed Homenday\u2019s comments. \u201cThe reason we operate under flight instruction regulations ... is that all of our customers take the controls of our aircraft under the supervision of one of our highly trained, certified flight instructors,\u201d spokesperson Megan Fazio said in a statement. Fazio said the company doesn\u2019t fit the FAA definition of an air tour operator, and \u201cour pilots have a higher level of certification than air tour operators require.\u201d Board members also suggested that better oversight might have prevented the 2019 Connecticut crash of a World War II-era bomber that killed seven people and the 2016 crash of a hot air balloon in Texas that killed the pilot and all 15 passengers. The NTSB blamed poor decision-making by the pilot as the probable cause of the balloon crash, the worst U.S. aviation accident since 2009. The NTSB made six new recommendations and reprised two previous ones to the FAA that would set new safety standards for certain revenue-making passenger operations and provide more guidance to FAA inspectors who monitor them.
