Use of Poke-Yoke for Right Manufacturing and Installation

Abstract

Hindustan Aeronautics Limited, Transport Aircraft Division, Kanpur manufactures HAL DO-228 a Light Transport Aircraft. Manufacturing of HAL DO-228 commenced as licensed production with Technology transfer from M/s Dornier GmbH, Germany. All the design data for manufacturing of parts, the manufacturing tooling and the processes were given under the agreement for Transfer of Technology. Number of aircraft have been built over a period spreading to more than two decades starting from the year 1984. In the recent years, we faced two distinct problems. One, defect occurred during manufacturing of two wing spar components. Another, operator faced problem due to wrong fitment of a part. We present these two interesting cases which were resolved by adopting poka-yoke methods.
