91.04.10 Flight recorders

 

(1) For the purposes of this regulation, any reference to—
(a) a specified date upon which an application for the type certification is submitted to a Contracting State means the date such application is made for a new aircraft type, not the date of certification of particular aircraft variants or derivative models; and
(b) a specified date upon which an individual certificate of airworthiness is first issued means the first time a certificate of airworthiness is issued for a new individual aircraft serial number that has just come off the assembly line.

[Regulation 91.04.10(1) substituted by regulation 9(b) of Notice No. R. 432, GG 40846, dated 19 May 2017 (Sixteenth Amendment of the Civil Aviation Regulations, 2017)]

 

(2) No owner or operator shall operate an aircraft engaged in international general aviation operations which—
(a) is an aeroplane with a MTOW exceeding 5700 kg for which the individual certificate of airworthiness was first issued on or after 1 January 2005 unless such aeroplane is equipped with a Type 1A FDR that complies with the requirements prescribed in Document SA-CATS 91;
(b) is an aeroplane with a MTOW exceeding 27000 kg for which the individual certificate of airworthiness was first issued on or after 1 January 1989 unless such aeroplane is equipped with a Type 1 FDR that complies with the requirements prescribed in Document SA-CATS 91;
(c) is a helicopter with a MTOW exceeding 3180 kg for which the individual certificate of airworthiness was first issued on or after 1 January 2016 unless such helicopter is equipped with a Type IVA FDR that complies with the requirements prescribed in Document SA-CATS 91; or
(d) is a helicopter with a MTOW exceeding 7000 kg or having a passenger seating configuration of more than 19, for which the individual certificate of airworthiness was first issued on or after 1 January 1989 unless such helicopter is equipped with a Type IV FDR that complies with the requirements prescribed in Document SA-CATS 91.

[Regulation 91.04.10(2) substituted by regulation 9(b) of Notice No. R. 432, GG 40846, dated 19 May 2017 (Sixteenth Amendment of the Civil Aviation Regulations, 2017)]

(6) No owner or operator shall operate an aircraft for which the individual certificate of airworthiness is first issued on or after 1 January 2016 and which is required to be fitted with a CVR or for aeroplanes, a CARS, unless the CVR or CARS, as applicable, is provided with an independent power source that complies with the requirements prescribed in Document SA-CATS91.

 

(7) No owner or operator shall operate an aircraft for which the individual certificate of airworthiness was first issued on or after 1 January 2016, which utilises any data link communications and is required to carry a CVR, unless all data link communications messages to and from the aircraft are recorded on a data link recorder (DLR) or other flight recorder. The minimum recording duration shall be equal to the duration of the CVR and shall be correlated to the recorded cockpit audio.

 

(8) No owner or operator shall operate an aircraft which is modified on or after 1 January 2016 to install and utilise any data link communications and is required to carry a CVR, unless the data link communications messages are recorded on a DLR or other flight recorder.

 

(9) The FDR required by this regulation shall be capable of retaining the information recorded during at least
(a) in the case of an aeroplane, the last 25 hours of its operation; or
(b) in the case of a helicopter, the last 10 hours of its operation.

 

(10) The CVR or CARS required by this regulation shall meet the specific recorded information time as prescribed in Document SA-CATS 91.

[Regulation 91.04.10(10) substituted by regulation 8(a) of Notice No. R. 3169, GG 48228, dated 17 March 2023 (Twenty-Fifth Amendment of the Civil Aviation Regulations, 2023)]

 

(11) No owner or operator shall use the following mediums to record any information or data required to be recorded by this regulation—

(b) from 1 January 2016, magnetic tape in FDRs and magnetic tape and wire in CVRs.

 

(12) The flight recorder shall not be switched off during flight.

 

(13) Each flight recorder installed in an aircraft shall be located and installed in such a manner that maximum practicable protection is provided, in order that, in the event of an accident or incident, the recorded data may be recovered in a preserved and intelligible state. Flight recorders shall meet the installation, crashworthiness and fire protection specifications prescribed in Document SA-CATS 91.

 

(14) The owner or operator of the aircraft shall ensure that retrieving the recorded data from the storage medium will be readily possible.

 

(15) The PIC, owner or operator shall ensure, to the extent possible, in the event the aircraft becomes involved in an accident or incident, that—
