Press Release
4iG SDT may acquire majority interest in a leading european helicopter maintenance company
The planned acquisition of a majority stake in the Hungary-based HeliControl represents a new market entry opportunity for 4iG SDT and may contribute to securing long-term helicopter maintenance and modernisation capabilities in the country and its wider region.
- 4iG Space and Defence Technologies Zrt. (4iG SDT Zrt.) signed a non-binding Term Sheet for the acquisition of a 63% majority stake in HeliControl Kft.
- Following the successful closing of the transaction, 4iG SDT Zrt. enters the rotorcraft maintenance, repair and overhaul (MRO) segment, a strategic area within the aerospace industry.
- In parallel, 4iG is pursuing another acquisition via N7 Defence Zrt., aimed at acquiring a majority stake in Aeroplex, Hungary’s leading aircraft maintenance and training company. The two transactions together could give the 4iG space and defence group a unique position in the Hungarian and European aerospace markets.
- The transaction may close following any required competition authority approvals.
4iG SDT Zrt., the space and defence technology subsidiary of the 4iG Group, signed a non-binding Term Sheet to acquire a 63%
stake in HeliControl Kft. Upon successful closing, the 4iG Group takes a significant step in expanding its defence and aerospace
portfolio by entering the rotorcraft maintenance and modernisation segment. The acquisition is expected to significantly strengthen
Hungarian helicopter MRO capacities, reducing the long-term dependence on foreign providers.
Founded in 2011 as a family-owned enterprise, HeliControl Kft. evolved into a regionally recognised service provider in the
rotary-wing segment. Initially focusing on helicopter maintenance, repair and spare parts supply, the company successfully
completed several major Airbus helicopter overhauls and rapidly expanded its structural repair certifications. Its commitment
to high-quality service soon earned recognition on international markets, attracting clients not only from Hungary but also
from Austria, Switzerland, Germany, Scandinavia, and other parts of Europe.
Among its professional milestones, HeliControl performed Hungary’s first night vision-compatible helicopter upgrade for the
Rapid Response Police's border surveillance fleet, with authorisation from the Hungarian Aviation Authority. The company received
regular commissions for military helicopter overhauls and successfully tendered for the Austrian Ministry of the Interior’s
contract for the full overhaul and spare parts supply of one of its police helicopters.
Another key milestone came in 2018, when HeliControl won a Hungarian Ministry of Defence tender, becoming the first company
in post-transition Hungary to carry out a full manufacturer-compliant overhaul on a Western helicopter type (AS350B). These
accomplishments positioned HeliControl as a trusted partner and preferred supplier to defence and law enforcement agencies
alike, and the company is an important partner to the Ministry of Defence and the Hungarian Defence Forces.
4iG SDT Zrt. recently expanded its aerospace portfolio through targeted acquisitions. Under a strategic agreement with the
Hungarian State, N7 Defence Zrt. — a 4iG Group company — is acquiring Aeroplex Kft., Hungary’s market-leading provider of
fixed-wing aircraft maintenance services. Also part of the 4iG defence portfolio is Rotors & Cams Zrt., which holds unique
expertise in the development and manufacturing of unmanned aerial vehicles (UAVs).
Once the HeliControl transaction is closed, 4iG SDT aims to establish a regional aerospace technology hub that brings together
the capacities and expertise required for the operation and development of fixed-wing, rotary-wing, and unmanned aircraft.
This would enable the 4iG Group to deliver integrated MRO services covering the entire lifecycle of aerial platforms across
both civil and defence domains.
The transaction closes following the required competition authority approvals.
