SIA TRITECH is an EASA Part-147 approved Maintenance Training Organisation based in Riga, Latvia. We deliver EASA Part-66 basic training and aircraft type rating courses under approval number LV.147.0004, issued by the State Agency “Civil Aviation Agency” of the Republic of Latvia.
TRITECH was established to provide technically rigorous, regulation-compliant maintenance training for engineers entering and advancing within the European aviation industry. We received our initial EASA Part-147 approval on 07 January 2015 and have maintained continuous regulatory oversight by the Latvian Civil Aviation Agency since that date. Our approval has been progressively expanded through six revisions, reflecting the addition of new aircraft type ratings and the ongoing development of our training facilities and instructional staff.
Based at Graudu iela 68, Rīga, Latvia, TRITECH operates from a dedicated training facility with classrooms, examination rooms, and practical training areas. Our instructors are experienced licensed engineers with direct operational backgrounds on the aircraft types we teach. The organisation is structured to deliver training in small, instructor-led groups — maintaining the depth and rigour that the regulated examination process demands.
TRITECH holds full examination authority under our Part-147 approval. This means that module examinations for EASA Part-66 basic training are conducted directly at our facility, without candidates needing to attend a separate examination centre or national authority. Upon passing each module examination, TRITECH issues a Certificate of Recognition (CofR) — the official evidence document submitted to the national aviation authority as part of the Aircraft Maintenance Licence application. This examination authority covers all four licence categories within our approved scope: A1, B1.1, B1.3, and B2.
For type rating training, TRITECH is approved to deliver theoretical and practical instruction across five major aircraft types: the Airbus A318/A319/A320/A321 family (CFM56 and IAE V2500 variants), the Boeing 737-600/700/800/900 (CFM56), the BAe 125 series (Honeywell TFE731), the Embraer EMB-135/145 (Rolls-Royce AE3007A), and the Embraer Phenom 300 / EMB-545/550 (Honeywell AS907). All type training is conducted under the regulatory scope of LV.147.0004.
Aviation maintenance training is a regulated, high-stakes activity. The individuals who complete our courses go on to hold legal certifying authority over commercial aircraft — their competence directly underpins flight safety. TRITECH approaches every training programme with that responsibility as its primary reference point. We do not operate as a volume training provider. Intake sizes are controlled, instruction is delivered by subject-matter experts, and examination preparation is taken seriously as a core function of the organisation rather than an afterthought.
Candidates who train at TRITECH receive a complete, documented record of their Part-66 module examinations and type training, issued by a single regulated organisation. This simplifies the AML application process and provides employers with a clear, verifiable training history from an authority-recognised source.
