FAA Delays Implementation of Mandatory Flight Deck Secondary Barriers by One Year

The Federal Aviation Administration (FAA) has announced a one-year delay in implementing its rule mandating secondary flight deck barriers on newly delivered US passenger aircraft. These barriers were originally scheduled to be required starting 25 August 2025. 

Secondary cockpit barriers, typically retractable metal gates, are designed to block access to the cockpit when the flight deck door is briefly opened, such as during lavatory breaks or crew changes. These barriers serve as a critical security layer against potential intrusions, especially in moments when the primary cockpit door is not secured. 

In the meantime, airlines are expected to continue relying on existing security procedures, such as positioning service trolleys to block access to the forward galley during cockpit door openings. 

This delay has drawn criticism from pilot unions. Capt. Jason Ambrosi, president of the Air Line Pilots Association (ALPA), called the move “deeply disappointing,” warning it weakens aviation security and citing a long history of industry resistance despite ample time for compliance. 

“This pattern of endless delays must stop,” Ambrosi said. “Airlines have had two years to prepare. This further postponement compromises the safety of our skies.” 

The FAA’s advisory circular AC No: 25.795-10, issued in June 2023, provides technical standards for Installed Physical Secondary Barriers (IPSBs) to comply with 14 CFR § 25.795(a)(4). These barriers must be lockable, tamper-resistant, and designed to be stowed during taxi, take-off, and landing. 

The rule applies only to newly manufactured passenger aircraft delivered after August 2025. It does not apply to cargo aircraft or foreign carriers operating in the United States. 

Calls for secondary barriers trace back to post-9/11 aviation reforms, which led to reinforced cockpit doors. However, concerns persisted about vulnerabilities when those doors are opened mid-flight. 

• 2004: United and Northwest Airlines install early secondary barriers

• 2007: ALPA urges federal mandate by 2010

• 2011–2020: FAA and industry groups study designs, costs, and procedures

• 2018: FAA Reauthorisation Act mandates secondary barrier rule

• 2023: Final rule issued requiring compliance by 2025

The FAA has previously estimated installation costs at $35,000 per aircraft, while earlier industry estimates ranged from $5,000 to $12,000. 

Despite widespread support from pilots and safety advocates, implementation has lagged due to airline pushback and logistical delays. 

As of now, the new compliance date is expected in 2026, although stakeholders warn that further postponements could undermine the regulation’s intent to strengthen in-flight security for passengers and crew.
