EASA 2019-0015

Supersedes and retains requirements of EASA 2006-0134, which requires replacement of certain circuit breaker (CB) switches, and expands the range of affected parts. It also requires replacement of P/N CM3589-20 CB switches with an improved design and replaces the previous life limit of 1,000 flight hours for certain P/N CM3589-50 CB switches, with a six-year calendar time life limit, and also imposes that limit on the improved-design CB switches.
