Crash Position Indicator CPI 503 series Emergency Locator Transmitter (ELT) - Limited Deployment Altitude

EASA Safety Information Bulletin SIB No. 2010-22 addresses the limited deployment altitude of the Crash Position Indicator CPI 503 series Emergency Locator Transmitters (ELTs) installed on various helicopter models including Eurocopter EC 155 B1, EC 225 LP, AS 332 L1/L2, AS 365 N2/N3, Eurocopter Deutschland EC 135 series, Agusta Westland A109 series, AB139, AW139, and Sikorsky S-61N, S-76 series, and S-92A helicopters. The bulletin highlights that these ELTs meet UK CAA specifications but do not fully comply with the JTSO/ETSO-2C126 EUROCAE ED-62 impact test criteria when deployed from high altitudes. A new model, P/N 503-16HT, has been developed to address this limitation.
