OGMA - Engine Services

TPE 331-5 / -10

The Engine Division of OGMA is an Authorized Repair Facility for Honeywell TPE 331-5 and TPE 331-10 turboprop engines as fitted to the CASA C-212 range of transport aircraft and to other similar aircraft types.

Over the last two decades OGMA has repaired and overhauled hundreds of these engines for the Air Forces of Portugal and other nations. The company is also approved by the European Aviation Safety Agency (EASA) to overhaul commercially operated -5 and -10 versions of the engine.

OGMA has full capability to carry out Hot Section Inspections and complete overhauls, as well as to embody repairs and to comply with Service Bulletins and other technical instructions. Our specialist engineering department is able to prepare individual customer workscopes and offer specialized solutions to specific engine problems.

Because of our superb repair capacity for engine internal and external parts we are able to offer considerable savings to our customers. In particular we have many years experience of carrying out extensive repairs for corrosion damage on the Accessory Drive Housing Assembly using thermal spray coatings in our modern robotic spray plant.

The company has specialized in-house workshops with repair and overhaul capability for all engine accessories and all the test equipment necessary to test and prove the repairs.

Following overhaul or major repair all engines are tested against a water dynamometer in our modern test cell. We also have the option of testing engines with a propeller on our outdoor cell, if circumstances require it. Of course, all engines ship with our comprehensive warranty.

Our Logistics Department is able to use its many years of experience to purchase parts from the OEM and other quality suppliers, thus reducing cost and Turn-Around-Time (TAT).

OGMA’s capacity to overhaul the CASA C-212 aircraft also makes it the ideal location for customers to experience our unique One-Stop-Shop approach to aircraft maintenance.

Recent and continuing improvements to our engine and component overhaul procedures have allowed us to become competitive in both price and Turn-Around Time while maintaining our renowned quality. Our position as one of the top independent T-56 shops allows us to choose parts and services from both the OEM and the best of the approved parts manufacturers - according with the choice and preference of our customers.

AE 3007 / 2100 /2100D3 In 1993 OGMA was appointed a Rolls-Royce Authorized Maintenance Center (AMC) for the AE 3007, AE 2100A and AE 2100D3 engines, being the sole independent European center of only six AMCs worldwide for these engines.
The AE 2100A powered SAAB 2000 turboprop regional aircraft was the first type to enter service using the AE family of engines and OGMA quickly became one of the main service centers for these engines. Since the entry into service of the Embraer ERJ135 / 145 regional jet aircraft, OGMA has consistently serviced a large number of AE 3007A engines for civil and military operators worldwide, including operators in Europe, North America and Asia and even for Rolls-Royce themselves. When the AE 2100D series commenced service in the Lockheed Martin C-130J Advanced Hercules, OGMA was one of the initial maintainers, working for the most of the major operators as well as Rolls-Royce and Lockheed Martin themselves. Lately OGMA has also acquired the capability to overhaul and repair the AE 2100D2 for the Alenia C-27 Spartan.
OGMA's Engineering Department has the experience to develop workscopes and repair schemes for our customers and to work to all the Rolls-Royce Customised Maintenance Plans. Over recent years the company has built up a comprehensive capability to carry out Rolls-Royce approved component repairs to these engines and can thus minimise the overall repair costs for demanding customers. With such a background, we are proud and confident to say that we are able to solve any technical problem that may appear, to find the most economical solution and to support our customers in obtaining maximum performance and profitability from their engines.

Despite the fact that company does not have a franchise to overhaul the Larzac engine, OGMA is a Turbomeca approved overhaul centre for other engines from their range. Therefore OGMA has some capability for component repair and overhaul, as well as a network of suppliers for other items.

Turmo III C 4 /IV C

OGMA is fully authorized both by Turbomeca and by the European Aviation Safety Agency (EASA) as a Repair Centre for the Turmo engines used in the Eurocopter SA330 Puma helicopter.

Over the last two decades OGMA has built up a vast knowledge of these rather complex engines, overhauling hundreds of examples for air force and civilian operators. In this time the company has become highly competent in solving the performance issues that frequently arise following rebuild.

Because of the small size and high performance of the Turmo, it is essential to work to the highest standards of quality and skill. These are areas where OGMA’s high level of technician training and skill give the company the edge. The customer benefits by obtaining the highest possible time between removals and performance margins.

All components of these engines can be overhauled in-house and most individual engine parts can be repaired to the demanding standards set by Turbomeca, because of the heavy investment made by the company in repair equipment and engineering.

Naturally OGMA works in accordance with the latest procedures and current manuals from the manufacturer and the Turboshaft engine test cell is correlated to Turbomeca’s own master cell. OGMA is proud to count Turbomeca themselves amongst the many satisfied customers who have benefited from our top quality Turmo engine overhaul services.

OGMA now has the capability to convert ex-military engines for civil applications, with the full authority vested in the company by its EASA certification. The engineering department is always available to assist with specific problems and to provide our customers with individual workscopes and detailed maintenance reports.

Artouste III B/B1/D

As the little Artouste engine nears the end of its expected service life, it is reassuring for the many remaining operators of the Alouette helicopter to find that maintenance, repair and overhaul of the highest quality is still available. OGMA still maintains a repair line with all the quality and capability which has made the company a leading Turbomeca Repair Center and European Aviation Safety Agency (EASA) repair station for many years, despite the reducing numbers of engines in service.

Over the last two decades OGMA has built up a vast knowledge of these first generation engines, overhauling hundreds of examples for operators worldwide. In this time the company has become highly competent in solving issues that frequently arise as engines reach “a certain age”. Indeed, Turbomeca themselves are aware of the issues peculiar to older engines operating in smaller numbers and OGMA is fully cooperating in exchanging information and skills with the OEM in order to keep these engines flying in complete safety.

Naturally OGMA works in accordance with the latest procedures and current manuals from the manufacturer and the Turboshaft engine test cell is correlated to Turbomeca’s own master cell. OGMA is proud to count Turbomeca themselves amongst the many satisfied customers who benefit from our top quality Artouste engine overhaul services.

OGMA has a highly professional engineering department, which is always available to assist with specific problems and to provide our customers with individual workscopes and detailed maintenance reports.
