Aerospace Engineering Consultancy

Engineering excellence for aerospace programmes

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.

Capabilities built for flight-critical programmes

Decades of combined experience across civil aviation, defence, and advanced air mobility — applied where it matters most.

Systems Engineering

Requirements management, architecture definition, and verification strategy for complex airborne and ground systems.

Certification & Compliance

Type certification, ARP4754A, DO-254, and CS/FAR support — translating airworthiness requirements into engineering action.

Programme Leadership

Technical programme management for clean-sheet aircraft, avionics upgrades, and integration campaigns — on cost, on schedule.

Safety & Reliability

Functional hazard assessments, FMEA, and system safety analysis aligned with SAE ARP4761 and the wider safety case.

Flight Test & Integration

Test planning, instrumentation strategy, and on-aircraft integration support — from rig through to first flight.

Engineering Leadership Coaching

Mentoring for chief engineers and technical leads navigating complex multi-disciplinary aerospace programmes.

An independent partner for serious aerospace work

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.
