Bell Helicopter [TXT] and PT Dirgantara Indonesia (Persero, PTDI) signed an expanded Industrial and Commercial Agreement to allow both companies to expand their support and services in Indonesia to Bell Helicopter operators, the company said Feb. 29.

First signed at Bell headquarters in Fort Worth, Texas, on Nov. 30, 2015, this extends an earlier agreement in place since 2012 while solidifying PTDI’s customization and delivery work for Bell 412 platforms. It also allows PTDI to enhance its relationship with other Bell customers and for additional commercial aircraft models, the company said.

Agreeing to extend their cooperation for five more years, the agreement allows PTDI to conduct joint sales and marketing, customization, aircraft delivery, aircraft component manufacturing, and aircraft maintenance.

 “We are very pleased to continue this agreement with PTDI and expand our operational capabilities in Indonesia. The region represents a significant growth opportunity for sales and operations, and we are pleased to continue our investment in the Asia Pacific market,” Mitch Snyder, president and CEO of Bell, said in a statement.

“PTDI and Bell Helicopter have been maintaining its cooperation for a longtime; nowadays both companies see growth with the Bell 412 market in Indonesia, so this cooperation is mutually beneficial to both companies,” Budi Santoso, president and director PTDI, added.

Bell said it has had a presence in Indonesia for over 50 years and fields over 100 aircraft supported by a Bell-authorized customer service facility and two dedicated full-time customer service engineers in the capital of Jakarta.

The agreement has previously served Indonesia’s armed services and the extension allows both companies to continue to provide these helicopter services to the government, the company said.

PTDI is an indigenous aerospace company in Asia with core competencies in aircraft design and development, aircraft structure manufacturing, aircraft assembly and aircraft services for civilian and military aircraft, Bell said. PTDI first established cooperation with aircraft companies including Bell in 1976.

By having an Industrial and Commercial Agreement, the two companies have agreed to extend the cooperation for the next five years that allows PTDI to conduct joint sales and marketing, customization, aircraft delivery, aircraft component manufacturing and aircraft maintenance.
