 As part of the 1976 modifications, various air scoops were moved and redesigned, offering a slight performance increase, while the extended wing tips reduced the stall speed from to in the 112A.Early models featured front seat three-point harnesses where the shoulder belt was fixed to the seat itself.This was found to offer too little strength and was replaced with one fixed to the fuselage behind the seat as part of a 1987 Airworthiness Directive (AD).
