I believe the 415 CD was meant be be flown either as a 415C or a 415D. The plane can fly in both weight limits by adjusting the elevator stop. Unfortunately there is no one that we can ask now, but I think the CAA did not approve it that way and added the CD to the TC 718, allowing a "conversion" to a 415 D that was already certified under TC787. I think this was the problem. The D-Model had already it's own Type Certificate. So they did not understand the need for another category in the old TC.
Hartmut From: Richard Wilkens Sent: Tuesday, April 06, 2010 2:56 AM To: [email protected] Subject: [ercoupe-tech] Normal/Utility. I have a question about Normal/Utility. I have an old 337 dated 7/31/47 for a radio installed by Parks Aircraft, one of the biggest Coupe dealers of the time. The aircraft is 415-CD. On the front of the 337 they give the following W&B information: Empty Weight: 827.75 Useful Load: Normal 572.25 Utility 432.25 Could a CD have been both a Normal (at 1,400) and a Utility (1,260)? The type certificate is "Pending." It has not been approved at his time. This was done by a company that knew Coupes. Any ideas? Richard NC99904
