Background 

On May 31, 2009, an Airbus A330– 

203 operated by Air France as flight 

number 447 (AF 447), bound for the 

Charles de Gaulle Airport, Paris, France, 

crashed into the Atlantic Ocean 2 hours 

and 10 minutes after taking off from Rio 

de Janeiro’s, Galea ̃o Airport. Search and 

rescue operations were conducted by 

the French and Brazilian authorities but 

the flight data recorder and cockpit 

voice recorder were not recovered until 

April 2011 during a fourth search and 

recovery effort. 

The Bureau d’Enqueˆtes et d’Analyses 

pour la Se ́curite ́ de L’aviation Civile 

(BEA), which is the authority 

responsible for the investigation of the 

AF 447 accident, released a second 

interim report, dated December 17, 

2009. The report includes safety 

recommendations to the European 

Aviation Safety Agency (EASA) and the 

International Civil Aviation 

Organization (ICAO), one of which is to 

‘‘extend as rapidly as possible to 90 

days the regulatory transmission time 

for underwater locator beacons installed 

on flight recorders on airplanes 

performing public transport flights over 

maritime areas.’’ The FAA agrees with 

the BEA’s recommendation, and via a 

letter dated January 28, 2010, requested 

that SAE International form an industry 

working group to revise the minimum 

performance standard (MPS), AS8045, 

Underwater Locating Devices (Acoustic) 

(Self-Powered), to increase the 

minimum operating life of Underwater 

Locating Devices (Acoustic) (SelfPowered), from 30 days to 90 days. SAE 

International published AS8045A, dated 

August 3, 2011. The FAA will revise 

TSO–C121a to invoke the new SAE 

standard. When TSO–C121b is 

published the FAA will withdraw TSO– 

C121 and TSO–C121a authorizations no 

later than March 1, 2014. All 

Underwater Locating Devices (Acoustic) 

(Self-Powered) equipment 

manufacturers seeking TSO 

authorization will need to obtain 

authorization to manufacture in 

accordance with TSO–C121b.
