The head of Boeing’s commercial airplanes division said the company hopes to announce a delivery schedule for its 787 aircraft within two weeks, but getting federal approval for fixes to the problem-plagued plane will be key.

Jim Albaugh, Boeing’s president and chief executive officer for airplanes, said that Boeing needs the Federal Aviation Administration “to agree to the fixes we’re going to put in place” and to restart certification test flights before the company can release a delivery schedule.

FAA official Laura Brown said the agency is working with Boeing on planning for a resumption of flight tests.

The 787 has suffered a string of production problems and is three years behind schedule.

Boeing resumed test flights of the plane in December after an in-flight fire halted them in November.
