Boeing 737 Aeroplanes equipped with Forward Airstairs
Summary
The FAA Special Airworthiness Information Bulletin SAIB: NM-07-47 addresses a safety concern for Boeing Model 737 series airplanes equipped with forward airstairs. It highlights a potential personal injury risk where small children may fall through openings in the airstair handrails during boarding or disembarking. The bulletin provides safety recommendations to mitigate this risk.
What Changed
SAIB NM-07-47 introduces recommendations to install warning placards on airstair steps and door jams, and to apply anti-skid material to the side beams and top stair of the forward airstairs. It also references Boeing and Monogram Systems service bulletins that address these safety enhancements and notes revisions to the flight attendant manual for increased vigilance around small children and persons with special needs.
Why It Matters
This bulletin is important for aviation professionals because it addresses a known safety hazard that could result in personal injury, particularly to small children. Operators and maintenance teams need to be aware of these recommendations to enhance passenger safety and reduce liability risks. Compliance with the recommended service bulletins can improve operational safety and passenger confidence during boarding and disembarking.
What To Do
Operators of Boeing 737 series airplanes with forward airstairs should incorporate Boeing Service Bulletin 737-52-1157 and Monogram Systems Service Bulletin 870700-52-2130. They should install warning placards and anti-skid materials as described, and update flight attendant procedures to monitor small children closely. No mandatory compliance deadline is specified, but prompt action is advised to mitigate injury risks.
