Last year the U.S. Federal Aviation Administration certified the Terrafugia Transition as airworthy.

年，美国联邦航空管理局为特拉弗吉亚汽车颁发了适航证。

And if it's airworthy, the aircraft is safe.

如果机是适航的，么它就是安全的。

An airplane undergoes a number of key  checks before a flight, so a technician needs to provide airworthy approval to the pilots  before they are cleared to commence operations.

机行前要进行多项关键检查，因此技术人员需要行员获准开始运营之前向他们提供适航许可。

Those in Canada and Europe are re-examining decisions to approve the 737 max based on mutual recognition agreements with America rather than trust the FAA they may order their own tests before certifying future bearing aircraft as airworthy

加拿大和欧洲的机构正重新审查基于与美国的相互认可协议批准737 Max系列机的决定，而不是完全信任美国联邦航空管理局。他们可能会认证未来机适航性之前自行进行测试。
