Spotlight on Volcanic Air

In Volcanic Air’s 206B JetRanger, it’s a relatively quick 20-minute flight from the shores of Lake Rotorua to the interior of New Zealand’s only active marine volcano: White Island. On the way, your pilot tells you about the local Maori people (the lake’s name means “lake two” in Maori), the Kaingaroa Forest (the largest human-planted forest in the world with more than 1100 sq miles of Monterey pines), and Captain James Cook’s naming of the island after either seeing steam rising from volcanic vents or the island’s supposed resemblance to a white whale.

White Island pokes up out of the surrounding Bay of Plenty and spews sulfur-laden steam from vents inside and outside its crater. Descending into the volcano’s edge and landing on a wood platform just a few feet wider than the JetRanger’s skid tubes at the edge of the volcano is nearly as exciting as subsequently hiking to the crater’s edge and peering down and across at about a dozen spewing vents, imagining the volcanic activity occurring inside the mountain. The breeze often carries just a whiff of sulfur odor, although filtration masks handed out by the Volcanic Air crew provide relief if the wind shifts.


Founded in 1992, Volcanic Air uses a mixed fleet of aircraft to conduct sightseeing flights from its base in Rotorua on the North Island. In addition to the sole JetRanger in its fleet (outfitted with VHA main and tail rotor blades), Volcanic Air operates Airbus H120 and 125 rotorcraft and Cessna 206 and Otter floatplanes. Passengers board the helicopters or floatplanes from Volcanic Air’s lakefront dock; at the end of the day the aircraft depart the dock for hangaring at nearby Rotorua International Airport.

Besides being one of only a handful of tour operators with permission to land on White Island, Volcanic Air also conducts sightseeing and charter tours of geothermal hotspots in the region with names like Hells Gate and Buried Village. Other air safari packages include wine tasting in the nearby Hawke’s Bay region, golf excursions, guided back country fishing, and a glow worm cave tour.


In addition to its main business of conducting air safaris, Volcanic Air offers rotorcraft and seaplane training, from type ratings and additional endorsements to biennial flight reviews.

For 206L LongRanger operators flying P/N 20633000-101 serial numbers A007-A009 or A012-A104, we would like to remind you that these blades are subject to AD 2022-22-08, which requires recurring tap inspections every 400 flight hours or 2,400 engine starts, whichever comes first. You can learn more about the tap test requirements and procedure in our video . These blades are likely to develop a delamination in the area of the weight pocket on the lower surface of the blade. The AD further requires removing the blades from service if the delamination reaches 6 inches in length. However, extensive company testing indicates that all blades will likely achieve their full retirement life before that occurs. So long as the delamination is monitored and does not exceed the permitted length, the blades are entirely safe to fly with no adverse effects on aircraft behavior or performance. Operators are required to report their findings at every inspection interval to VHA for tracking using the form on the last page of Service Bulletin 33000-4 . Completed forms should be emailed to info@vanhornaviation.com . Providing this data helps to ensure all operators of these blades remain safe. All of the identified blades are likely to have delaminations, so if none are detected please contact us for assistance. In addition, this AD is considered an interim action and once sufficient data is gathered it may be updated to reduce the required frequency of inspection. Refer to AD 2022-22-08 and SB 33000-4 for further information.
