Worn Fuel Primer Pumps Lead to Loss of Engine Events on General Aviation Aircraft
The FAA is investigating a report of a worn fuel primer pump that may be installed in general aviation aircraft following a non-fatal accident on a Champion 7EC Traveler. During the initial takeoff climb, the pilot noticed a significant decrease in the engine rpm and lost full engine power shortly after. It was determined that the fuel primer pump in the accident was worn and unable to lock properly causing an overly rich fuel mixture. The airplane sustained substantial damage to the right wing and the fuselage. FAA's Operational Safety Branch recently issued an Airworthiness Concern Sheet to highlight this concern and included photographs of the wear on the fuel primer pump. The FAA is recommending operators inspect all manual fuel primer pumps found on general aviation aircraft with carburetor engines and provide information including description of damage, available photos, airplane serial number, time in service, and any prior replacement of the manual fuel primer pump.

HNL TAXIWAY C Restrictions through April 16, 2025
HNL TAXIWAY(TWY) C RESTRICTIONS DURING SHOULDER CONSTRUCTION PHASES 6A & 6B TWY C Aircraft Wingspan Restrictions, 16 March – 16 April, 2025; TWY C between TWY F and TWY RT is restricted to a 52’ wingspan; aircraft with wingspans exceeding 52’ must use alternate routes. TWY RT Closure: March 15, 2025 – March 28, 2025:  TWY RT will be closed between TWY C and TWY R with no access to TWY RT in this segment during the closure period. TWY C Shoulder Work (Between TWY RT and F), March 15, 2025 - April 16, 2025: Shoulder rehabilitation work will be done on TWY C, extending through TWY F.  NOTE: Either the North or South entrance to the Tie-down/T-hangar area will remain open. Exercise caution in this area due to ongoing construction activity.   POC: Thomas Waldman: email: thomas.j.waldman@hawaii.gov; phone: (808) 836-6661  
USHST Monthly Safety Report for March 2025
  US Helicopter Safety Team (USHST) Monthly Safety Report March 2025   USHST Vision:  A civil registered helicopter community without fatal accidents Days since last Fatal helicopter accident:  7 Days : 21 Hours : 7 Minutes : 56 Seconds   US Helicopter Safety Team (USHST) Calendar Year Metrics - The USHST began tracking its new goals for the CY2025-2029 (5 year) timeframe. The goals are by 14 CFR Operating Part, tracking the 5 year average fatal accident rates per 100K hours.   14 CFR Part Baseline, CY2018-2022 (per 100K hours) Goal, CY2025-2029 (per 100K hours) Progress, CY2021-2025 (per 100K hours) 91 0.81 0.73 (10% reduction) 0.6 133 1.73 1.56 (10% reduction) 0.42 135 0.33 0.17 (50% reduction) 0.34 137 1.11 1.00 (10% reduction) 1.46 USHST uses the following as conditions for the fatal accidents included in rate calculations:  U.S. registered aircraft, Operating in the U.S./U.S. territories (includes offshore), Not operating as Public Aircraft (public use). Helicopter - Safety Enhancement (H-SE) Details   H-SE 23-01: Professional Preflight Planning & Go/No-Go Aeronautical Decision Making (P3-GADM) The primary objective of this safety enhancement is to help prevent fatal helicopter accidents that can be directly or indirectly linked to preflight judgment errors, decision-making errors, and inadequate mission planning. The H-SE team led by the HAI Safety Working Group will develop and deliver sources that will likely include policies, procedures, practices, tools, and other resources/tools that when implemented correctly, can prevent future fatal rotorcraft accidents attributable to flawed, inappropriate, and unauthorized preflight GO/NO-GO decisions. To frame the objective in a more positive manner, the team seeks to make it easier for flight planners to make well-informed GO/NO-GO decisions that are correct, appropriate, authorized before every flight, and independent from potential internal or external pressures, influences, or other factors.  Helicopter Safety OUTREACH events: All Hands Seminar at VERTICON  (March 10, 2025, 2:25-4:15pm, Room D163/165) FAA seeks responses for 2024 GA Survey - Vertical Aviation International USHST Winter 2025 Newsletter The Resilience Hub    JOIN/FOLLOW USHST USHST Facebook (3249 Members)                USHST LinkedIn        Please refer to USHST.org to view this entire safety report.

Wake Turbulance Advisory
Pilots must exercise extreme caution if there's any possibility of wake turbulence from a heavier airplane (or helicopter!). There've been two accidents at Kalaeloa (JRF) Airport since December 2023, so we've have lost focus on the absolute necessity of treating wake turbulence with the utmost respect. We'll provide a very brief review but a detailed study of wake turbulence is beyond the scope of this Notice. Accordingly, pilots are encouraged to review this vital topic and also discuss it with their CFIs.  Per the Pilot's Handbook of Aeronautical Knowledge: "Wingtip vortices are greatest when the generating aircraft is "heavy, clean and slow"...most commonly...during approaches or departures...To minimize the chances of...wake turbulence: 1) Avoid flying through another aircraft's flight path; 2) Rotate prior to the point where the preceding aircraft rotated; 3) Avoid following another aircraft...within 1,000 feet below their flight path; 4) Approach...above a preceding aircraft's flightpath and touch down past the point (where) the other aircraft wheels contacted the runway. Helicopter vortices should be avoided because helicopters...can generate exceptionally strong wake turbulence...small aircraft should avoid a hovering helicopter by at least three rotor disk diameters. Wind is important...in avoiding wake turbulence because vortices drift with the wind...10 knots (wind speed) causes the vortices to drift at about 1,000 feet in a minute...If a pilot is unsure of the other aircraft's takeoff or landing point, approximately 3 minutes provides a margin...that allows wake turbulence dissipation.  For more info...see Advisory Circular (AC) 90-23, Aircraft Wake Turbulence."
