SG Birch Services Limited partners with aerospace and defence organisations to deliver robust systems engineering, certification support, and programme leadership — from concept through to flight.
Decades of combined experience across civil aviation, defence, and advanced air mobility — applied where it matters most.
Requirements management, architecture definition, and verification strategy for complex airborne and ground systems.
Type certification, ARP4754A, DO-254, and CS/FAR support — translating airworthiness requirements into engineering action.
Technical programme management for clean-sheet aircraft, avionics upgrades, and integration campaigns — on cost, on schedule.
Functional hazard assessments, FMEA, and system safety analysis aligned with SAE ARP4761 and the wider safety case.
Test planning, instrumentation strategy, and on-aircraft integration support — from rig through to first flight.
Mentoring for chief engineers and technical leads navigating complex multi-disciplinary aerospace programmes.
SG Birch Services Limited was founded to give aerospace organisations access to deep engineering judgement when it counts — in early architecture decisions, in tense certification reviews, and in the integration phases where small problems compound quickly.
We work side-by-side with engineering teams, programme offices, and executive leadership. Our remit is simple: reduce technical risk, unblock decisions, and leave behind capability your organisation keeps.
Whether you are scoping a new aircraft, navigating certification, or looking for an experienced second pair of eyes — we'd be glad to hear from you.
