Legal Interpretation of 14 C.F.R. § 121.711

*1 This is in response to your October 21, 2009 request for a legal interpretation regarding the obligations under 14 C.F.R. 

§ 121.711 of certificate holders to record each en route radio contact between the certificate holder and its pilots. Specifically, 

you note that many certificate holders use various electronic recording device mechanisms to comply with § 121.711, but that 

some operators record only the time of day and the flight number. You ask for an interpretation from this office to ascertain

what the Administrator believes to be the minimum required content of a record under § 121.711. At a minimum, records of 

en route ratio contact under § 121.711 should include the time and date of the radio contact, the approximate position of the 

aircraft, the aircraft registration number, the flight call sign, and a narrative of the conversation.

As provided in § 121.711, “[e]ach certificate holder conducting domestic or flag operations shall record each en route radio 

contact between the certificate holder and its pilots and shall keep that record for at least 30 days.” Section 121.711 is a 

recodified version of 14 C.F.R. § 40.512, which provided that “[e]ach air carrier shall maintain, and retain for a period of 30 

days, records of radio contacts by or with pilots en route.” The rationale behind this rule, as stated in the preamble to §

40.512’s notice of proposed rulemaking, is to “enable the [Civil Aeronautics] Board and the Administrator to discharge fully 

their respective accident investigation and safety regulatory responsibilities.” See 23 Fed. Reg. 7723 (Oct. 7, 1958). A 

notation of only the time of day and flight number would not be sufficient to allow the Administrator and the National 

Transportation Safety Board to fully discharge their respective accident investigation and safety regulatory responsibilities.

First, if communication regarding safety of flight that is being communicated with the certificate holder is not recorded and a 

cockpit voice recording is unrecoverable, information that might be needed to reconstruct an accident or incident will not be

available. Cf. 49 C.F.R. § 830.10(d) (“The operator of an aircraft involved in an accident or incident shall retain all records, 

reports, internal documents, and memoranda dealing with the accident or incident, until authorized by the [National 

Transportation Safety] Board to the contrary.”).

Second, existing regulatory guidance materials provide that, “[i]n general, a record must show what event occurred, to whom, 

by whom, when, and proof of the event’s occurrence, such as a certification by signature or by electronic means.” FAA Order 

8900.1, Vol. 3, Ch. 31, § 1, par 3-2982(A) (“A record is defined as an account which preserves evidence of the occurrence of 

an event.”). Hence, a notation of only the time of day and flight number fails to describe what event occurred meriting the 

radio contact, who made and received the radio contact, on which date the radio contact took place, and on which particular 

aircraft such radio contact took place. Therefore, at a minimum, § 121.711 requires the time and date of the radio contact, the 

approximate position of the aircraft, the aircraft registration number, the flight call sign, and a narrative of the conversation.
