How Heliport Approval Works in Saudi Arabia Under GACAR Part 138

Getting a helipad approved in Saudi Arabia runs through the General Authority of Civil Aviation under GACAR Part 138, the regulation covering heliport design, construction and operation. The process is not a single submission and a stamp. It is a sequence of gates, starting long before a foundation is poured and continuing after the helipad is already receiving flights.

Who actually applies

The applicant is normally the owner or operator of the facility the helipad serves, a hospital, a private estate, an industrial site, or a commercial operator building a dedicated landing area. GACA does not deal with a demolition crew or a lighting supplier directly. The applicant carries the file, and the engineering, design and equipment suppliers around the project feed it the technical package it needs. This matters early, because a project that starts civil works before anyone has confirmed the site meets siting criteria under Part 138 risks discovering a compliance problem after concrete is already down.

The aeronautical study comes before design, not after

An aeronautical study is the technical justification that a proposed helipad location and layout can be operated safely. It looks at approach and departure paths, obstacles in the surrounding terrain and buildings, prevailing wind, elevation, and how the site interacts with any nearby aerodrome traffic. For a rooftop hospital helipad in a dense urban area, this study is where most of the real constraints surface, because the aeronautical study is what determines whether the touchdown and lift-off area can even go where the client originally wanted it. Skipping this step, or treating it as a formality, is the single most common reason a helipad design has to be reworked mid-project.

Forms and the documentation package

GACA's Part 138 process runs on a defined set of application forms and supporting technical documents, covering site details, the aeronautical study findings, physical characteristics of the touchdown and lift-off area and any final approach and take-off area, marking and lighting intent, and the operational procedures the site will follow once live. The exact form set is published by GACA and should be pulled directly from the regulator rather than assumed from a prior project, since heliport types (hospital, private, public use) carry different documentation expectations under Part 138. A complete package moves faster through review than a partial one resubmitted in pieces.

The typical gates a project moves through

Most Part 138 heliport projects move through a recognizable sequence: site and aeronautical study submission and review, a design approval stage covering the physical layout, markings, and lighting plan against Part 138 and the relevant ICAO Annex 14 Volume II provisions it draws on, a construction and installation phase carried out to that approved design, and a final inspection before an operational approval is issued. Each gate can generate comments or required changes, and a design that drifts from the version GACA reviewed at the design-approval stage, even a minor one, tends to trigger a fresh review rather than a quiet sign-off. Building to the approved drawings, not to a value-engineered variant of them, keeps the final inspection from becoming another design conversation.

Where lighting and marking approval fits

Heliport lighting, perimeter lights, floodlighting, TLOF and FATO markings, and any approach path indicators are part of the design package GACA reviews, not an afterthought bolted on after civil works. Equipment specified to recognized photometric and installation standards under ICAO Annex 14 Volume II gives the design submission a stronger technical basis than generic fixtures with no stated compliance basis. This is also where a mismatch between what was submitted on paper and what gets installed on site tends to surface at final inspection, since inspectors are checking installed condition against the approved drawing set.

Maintenance and recurring compliance after approval

Approval under Part 138 is not the end of the regulatory relationship. A heliport in active use has ongoing obligations around maintaining marking and lighting condition, keeping the surrounding obstacle environment consistent with what was approved, and following the operational procedures documented in the original submission. A hospital helipad that changes its surrounding building height, adds a rooftop structure, or lets lighting degrade without maintenance is drifting away from its approved basis, which is a problem that surfaces at the next inspection cycle rather than immediately.

Where projects lose time

The recurring pattern in delayed Part 138 approvals is sequencing: civil or structural works starting before the aeronautical study and design approval are settled, lighting and marking specified generically instead of against a named standard, or a documentation package submitted piecemeal instead of complete. None of these are technically difficult problems. They are project-management problems that show up as regulatory delay. NLS supports helipad and heliport projects in Saudi Arabia with lighting, marking and obstruction infrastructure engineered to ICAO Annex 14 Volume II and installed to align with GACAR Part 138 design submissions.

FAQ

Q: Who is responsible for submitting the GACAR Part 138 heliport application in Saudi Arabia? A: The facility owner or operator, such as a hospital or a private site operator, is the applicant of record with the General Authority of Civil Aviation. Design engineers, contractors and equipment suppliers support the technical package, but the application itself sits with the party that will operate the heliport.

Q: What does an aeronautical study for a helipad actually assess? A: It assesses whether the proposed location and layout can be operated safely, covering approach and departure paths, surrounding obstacles, prevailing wind, elevation and interaction with nearby aerodrome traffic. It is usually the stage that determines whether a preferred site location is workable at all, so it should happen before detailed design, not after.

Q: Can helipad construction start before GACA design approval is issued? A: Starting civil or structural works ahead of design approval carries real risk, because any change GACA requires at the design-approval stage can force rework of work already built. The safer sequence is aeronautical study, then design approval, then construction to the approved drawings.

Q: Does a hospital helipad need different approval steps than a private helipad in Saudi Arabia? A: Heliport type affects the documentation expectations under Part 138, since public-use and hospital facilities carry different operational and siting considerations than a private landing area. The underlying process, aeronautical study, design approval, construction, final inspection, stays the same, but the technical detail expected in each submission varies by facility type.
