NBAA and AOPA late last week sent a joint letter to the TSA asking the agency to double the 60-day comment window for the Large Aircraft Security Program proposal, which would cover all Part 91 operators flying aircraft with an mtow exceeding 12,500 pounds. “This proposal represents a significant regulatory change in the conduct of private aircraft operations,” states the letter signed by NBAA president and CEO Ed Bolen and AOPA president Phil Boyer. “We believe that the 60-day comment period is insufficient to provide the TSA with answers to the substantial number of questions posed in the proposal and to provide sufficient time for community education and feedback...We believe the TSA will benefit substantially from a 60-day extension to the comment period and the use of public meetings.” In a meeting with TSA Administrator Kip Hawley, Bolen expressed disappointment that the proposed rule appears to have been written with commercial operations in mind. “Whatever is done to promote security [must] be tailored to the operation and the risk involved,” he said. “It also has to be prudent, effective, reasonable and workable. This proposal does not appear to be in line with those principles. I think our comments will be substantial.” NBAA is urging individual operators to submit comments on the TSA proposal.
