Background: The FAA has advised that a potential exists for contact between an occupant of the crew rest compartment and the sidewall- mounted reading lights on aeroplanes that have been modified in accordance with STC ST00973WI-D. Sustained contact between the occupant and the reading lights could result in possible injury to the occupant. Additionally, inadvertent contact could also occur between various flammable materials (sheets, blankets, flightcrew clothing) and the sidewall- mounted reading lights. Such contact between the flammable materials and the reading lights could cause charring or melting of the heated material and consequent emission of toxic or noxious gases.
