LONDON (MarketWatch) -- United Airlines on Wednesday became the latest airline to ground planes, saying it won't fly 52 Boeing 777s until safety tests are completed.
The unit of UAL Corp. (UAUA:23.13, +1.60, +7.4%) said it discovered that a routine pre-flight safety check, a test on the firing systems on one of the "bottles" in the cargo fire suppression system, was not performed.
United said it voluntarily disclosed that to the Federal Aviation Administration and is grounding that aircraft until the tests are completed.
There may be delays and cancellations on Wednesday, United said.
United joins Southwest Airlines (LUV:12.75, +0.35, +2.8%) , American Airlines (AMR:9.85, +0.83, +9.2%) and Delta Air Lines (DAL:9.14, +0.54, +6.3%) in having to ground aircraft to perform safety tests.
