American Airlines’ pilots union is sounding the alarm about ‘problematic trends’ in air safety

Though United Airlines made headlines last month for its industry-leading number of Federal Aviation Administration-noted incidents, it seems like it’s not the only airline having trouble maintaining high safety standards.

Bloomberg reports that the Allied Pilots Association, the union that represents pilots for American Airlines, issued a memo to members Friday warning them to remain “vigilant” amid a “spike” in safety problems.

“While United Airlines is currently under public and government scrutiny, it could just as easily be American Airlines,” the union said, according to a copy of the memo provided to Quartz.

Among the “problematic trends” identified by the union were tools being left in plane wheel wells, a reduction in quantity and quality of maintenance checks, and pressure to quickly return planes to service despite fewer aircraft inspections.

“Remember: Don’t rush, don’t be intimidated, and don’t be pressured into doing something that doesn’t pass the ‘smell test,’” the memo reads. “Just because it’s legal doesn’t make it safe.”

In the wake of mid-flight door plug blowout aboard an Alaska Airlines-operated Boeing 737 Max 9, the airline industry has come in for a lot more scrutiny regarding operational safeguards. Boeing has been the biggest focal point, but it hasn’t been the only one. After its bumpy March, United executives told their workforce that the FAA would be supervising the company more closely.

American Airlines did not immediately respond to a request for comment. At its Investor Day last month, the company trumpeted its safety record.

“We’re running an operation that delivers on the capacity we guided to what our customers, our shareholders and our team can trust,” COO David Seymour told attendees. “It’s an operation built on a strong safety foundation that is bolstered by our industry-leading safety management systems.”
