New York (CNN Business) Boeing had no new orders for planes in April.

Not only did the troubled 737 Max receive zero new orders since it was grounded March 13. Boeing's other jets, such as the 787 Dreamliner or the 777, also did not get any new orders last month, according to a company report released Tuesday.

Boeing BA did report some orders for the other jets in late March, even in the wake of the March 10 crash of an Ethiopian Airlines jet and the grounding of the 737 Max that followed. Lufthansa ordered 20 of the 787 jets on March 15, and British Airways ordered 18 of the 777X on March 22.

But the only orders reported by Boeing for April were bookkeeping entries: Four 737 Max jets that had been sold to Boeing Capital in the past were transferred to an unidentified lessor last month. Boeing didn't count those as new orders. Instead, it reclassified sales it had already reported in the first quarter.

None of Boeing's other jet models have crashed, and airlines have not reported any safety problems other than the 737 Max. But the 737 Max's problems could be the reason airlines put orders for the other jets on hold, said Philip Baggaley, the lead credit analyst for the transportation sector for Standard & Poor's.
