Titled “Impact of shutdown on NTSB investigations and related activities,” the memo is dated January 25, 2019, and gives details of some of the major investigations halted due to the shutdown.

In addition to the domestic incidents, 12 foreign investigations involving U.S. operators or products were also suspended.

The NTSB did not launch investigations into several serious accidents that occurred during the shutdown. One of them was the Jan. 3 collision of a tractor trailer with a van bound for Disney World. Another incident took place in Atlanta, Georgia, in which an aviation accident killed four people. One accident taking place in Guam Naval Base involved a “major marine casualty.”

The NTSB also suspended ongoing investigations of two naval collisions: the USS Fitzgerald near Japan, and the USS John S. McCain near the Straits of Singapore.

The memo also shows that 367 of 397 NTSB staff were furloughed, with only four staff members being recalled and 26 excepted.

Research and engineering which NTSB conducts in support of its investigations was also suspended, including 63 medical and materials laboratory cases.

Several of the suspended investigations pertained to pipelines and hazardous materials accidents. For example, the memo cites a natural gas explosion in Merrimack Valley, Massachusetts, an Enbridge pipeline release of natural gas, and an “unknown” amount of diesel fuel released into a tributary.

After becoming the longest government shutdown in U.S. history — by a wide margin — the shutdown was temporarily ended when President Trump signed a bill reopening the government for three weeks. Without a deal by February for a border wall, Pres. Trump has threatened to shut down the government again.

The NTSB did not immediately respond to a request for comment.
