Certification Basis FAR 21.29 and FAR 33 effective February 1, 1965, as
amended by Amendments 33-1 through 33-9, inclusive.
Pursuant to FAR 21.29(a)(1)(ii) the type certificate was
issued in validation of the British Civil Aviation
Authority (CAA) certification to British Civil
Airworthiness Requirements, BCAR Section C Issue 13,
dated August 28, 1981, which were found to provide a
level of safety equivalent to the above FAR 33 regulations.
Import Requirements Each individually imported engine must be accompanied
by a Rolls-Royce Limited/CAA approved "Inspection and
Test Certificate" signed by a person authorized by the
CAA and containing the following statement: "The
engine covered by this certificate conforms to Type
Certificate E19NE and is in condition for safe operation
and has been subjected by the manufacturer to a final
operational check."
