A JAL MD-90-30 (JA8004) landed at Kagoshima (KOJ) with the nr.1 engine thrust reverser locked. Flight 3913 from Osaka-Itami (ITM) landed without problems, but the company was given a verbal warning by the Ministry of Land, Infrastructure and Transport. It appeared that a mechanic forgot to remove the safety pin locking the engine thrust reverser during maintenance operations. JAL had a similar maintenance problem last July. (Kyodo, NHK)
