Ercoupe #1320 LSA Gross Weight Increase

STC SA02450CH – Authorization and Instructions - No Parts Required in Most Cases

This 60-Pound increase in Gross Weight will provide the operator with a greater margin of safety through the ability of the average aircraft to carry a full fuel load (24 Gallons) and two (2) 170-Pound occupants.

Elevator and Trim Tab Requirements

The subject 415-C and CD Aircraft must incorporate a longitudinal control system meeting the following:

• Elevator - Full span elevator (ERCO Drawing 415-22017, with a moveable 1 3/8 trim tab cut into the right trailing edge. (ERCO Drawing 415-22031)
• or Elevator - Split elevator assembly (ERCO Drawing 415- 22037)
• and Trim control - Cabin wall (415-C) or console mounted control. (415-CD)
  

Discussion

There are three styles of elevators that may be found installed on Model 415-C and 415-CD aircraft.
415-C Aircraft were originally equipped with a full span elevator (ERCO Drawing 415-22001), without
moveable trim tab. Elevators, per drawing 415-22001 do not fulfill the requirements of this STC.

Later 415-C Aircraft were equipped with a full span elevator (ERCO Drawing 415-22017), with a moveable trim tab, cut into the right trailing edge. (ERCO Drawing 415-22027)
Aircraft with trim tabs per ERCO Drawing 415-22027 will need to be updated with the installation of PN 415-22031-4, 1 3/8 trim tab blade, per ERCO Drawing 415- 22031.

415-CD Aircraft were equipped with a full span elevator (ERCO Drawing 415-22017, with a moveable 1 3/8 trim tab cut into the right trailing edge. (ERCO Drawing 415-22031).

These installation conform to the requirements of STC SA02450CH.

415-C and 415-CD Aircraft, Model E split elevator. An unknown number of 415-C and 415-CD aircraft have been field modified and FAA approved to incorporate the split elevator assembly (ERCO Drawing 415- 22037), first seen on Model 415-E aircraft.

It has been determined that a properly rigged E model elevator assembly satisfies the requirements of this STC.
