The Saab 340 flight crew noted the broken door seal seat during a preflight inspection but incorrectly believed that it was a cosmetic problem reported by another crew the previous day. During climb-out after a takeoff from Canberra Airport, however, the cabin altitude was higher than normal; the crew descended and kept the airplane below 10,000 ft for the flight to Sydney, the Australian Transport Safety Bureau (ATSB) said.

Two flight crews failed to anticipate that the broken door seal seat would interfere with pressurization of the Saab 340, the ATSB says.
