61.165(c) lays out adding a ME to an ATP under the new rules.
I disagree. Section 61.165(f) address this situation specifically:
(f) Adding a multiengine class rating or airplane type rating to an airline transport pilot certificate with a single engine class rating. A person applying to add a multiengine class rating or airplane type rating to an airline transport pilot certificate with an airplane category single engine class rating must—
(1) Meet the eligibility requirements of §61.153;
(2) After July 31, 2014, pass a required knowledge test on the aeronautical knowledge areas of §61.155(c), as applicable to multiengine airplanes;
(3) Comply with the requirements in §61.157(b), if applicable;
(4) Meet the applicable aeronautical experience requirements of §61.159; and
(5) Pass a practical test on the areas of operation of §61.157(e)
My interpretation is: if you get your single-engine ATP now, you can add the multi-engine class down the road
without completing a CTP. However you will still need to take the new (and improved!) written exam that is specific to multi-engine airplanes.
Anybody disagree?
