Get an email when the record for Sierra Nevada Meml Hospital changes: its FAA registration, pad data, nearby FAA airspace determinations, or AirIndex findings. A weekly digest arrives only when something changed.
FAA status: Open. Last FAA inspection: none on record (common for private-use pads, which the FAA does not routinely inspect). Last update from the owner: 2025/05/28. Our check of the record: Corroborated (details below).
What has the FAA said about its airspace?
1 FAA airspace determination is linked to this site; the airspace finding on file is on_file. The list is below.
What is being built nearby?
No FAA obstruction filings (cranes, buildings, towers) within 1 nm in the last 12 months.
Where else can aircraft land nearby?
No other open FAA-registered landing site within 15 nm.
To correct it, the facility manager signs in to ADIP and uses Airport Master Record, Update Facility Data (Airport/Heliport). The paper private-use form 5010-2 was retired in July 2024.
Building, changing, reopening or closing a landing site needs notice to the FAA on Form 7480-1 (14 CFR Part 157).
AirIndex compiles public FAA, federal and hospital records and checks them against each other. It is not a source for navigation or flight planning; use official FAA sources and your operator's procedures. See something wrong? Report a correction (how corrections work).

Obstruction screen
Obstructed
Obstruction within 0.5 nm on the FAA obstacle file.
Geometry
Requires 75 feet of expansion
Recorded pad side 25 ft against a 100 ft eVTOL FATO.
Structural FATO
Unverified
The full 100 × 100 ft FATO must be load-bearing. The FAA does not record structural capacity, so no record can confirm it.
Overall
Constrained
Obstruction within 0.5 nm plus the required footprint expansion. Site validation required.
The recorded pad is 75 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

Load-bearing FATO
100 × 100 ft must be structural
No heliport precedent — typically the binding gate for rooftop and hospital pads.
Measured against FAA pad geometry and federal FATO sizing (EB-105). The obstruction screen is the only reading the engine verdict rests on; geometry and structural capacity are stated separately and never folded into it. A dimensional pre-screen — site-level validation required, and independent of the underwriting risk score.

3Physically verifiedGround Truth capture
Obstructions, exact FATO geometry, surface condition, and downwash exposure require a physical Ground Truth capture — not shown above as measured. A field verification completes the record and writes the measured truth to this facility’s authority.
This page is the public data-integrity record. The full RiskIndex assessment — Q1–Q5 compliance, dimensional / FATO analysis, an underwriting-grade risk score, peer benchmark, and a sealed Site Intelligence Report — is available on request.
