This STC was developed in order to improve the handling, landing performance and safety of certain Univair (ERCO) 415-C, -CD, - D aircraft through the installation of the later Model "E" split elevator assembly (Drawing 415-22037) and Low Speed Warning Cushion (Drawing 415-52025). This installation improves the slow speed handling and landing performance of the aircraft without sacrificing the anti-spin characteristics of the design. Required Changes: This effort will require that candidate 415-C aircraft be modified, if not previously accomplished, to include an elevator trim tab control system. Univair Installation SK-4. The Modification of 415-C, -CD and -D aircraft will include installing an "E" elevator assembly (415-22037), center hinge (415-22038), elevator control arm (415-52024), spring (415-22026) and link (415-52027); plus attaching hardware to complete the Low Speed Warning Cushion. |
