(16) Aircraft components or systems 

that result in taking emergency ac-

(b) For the purpose of this section,

(c) In addition to the reports required 

by paragraph (a) of this section, each 
program manager must report any 

other failure, malfunction, or defect in 
an aircraft that occurs or is detected at 
any time if, in the manager’s opinion, 
the failure, malfunction, or defect has 
endangered or may endanger the safe 
operation of the aircraft. 

(d) Each program manager must send 

each report required by this section, in

(7) Other pertinent information nec-

essary for more complete identifica-
