PARIS, Nov 13 (Reuters) - Turboprop aircraft maker ATR

said on Wednesday it would scrap development of its latest

model, designed to take off and land on short runways, and

concentrate on its existing portfolio.

The French-Italian company, co-owned by Airbus and

Leonardo, said the decision to halt the new ATR

42-600S Short Take-Off and Landing (STOL) development followed

an extensive market review and lingering supply chain tensions.
